Chapter 23: Loyal Idiots and Lightning Storms

Notes:

Hello, my beautiful readers! I hope you've all had a good week!

I Hope you enjoy this chapter, it's a bit of a cliché, I can't lie, but it's a cliché because it's SOOOO GOOOOOD! Also, I like to think I've added my own little spin on it in Lily's case.

Enjoy! See you at the end :)

(See the end of the chapter for more notes.)

Chapter Text

The weeks slipped by softly, marked by the steady rhythm of training and laughter.
Tobias’s new program grounded them — quite literally. No broomsticks, no glamour, no shortcuts. Feet stayed on the earth, lungs filled with morning mist, and muscles burned with the simple work of strength and stamina. They ran laps around the manor grounds until dawn turned the sky gold, sparred until the air smelled of sweat and effort, and learned to trust their own balance again. Even Sirius stopped complaining after the first week — mostly because no one had the breath left to listen.

By Friday, the exhaustion shifted into something lighter. The week’s discipline melted into laughter, into music, into the pulsing warmth of Sullivan’s.
The familiar scent of beer and sugar drifted through the air, and Sevessa stood once again beneath the dim stage lights, her voice curling through the haze like smoke. She didn’t sing so much as weave — threads of sound and magic twining together until the room held its breath to listen. Lily danced until her cheeks flushed pink, Jem and Cal threw themselves into the rhythm, and even James let his shoulders drop long enough to laugh. For a few hours, they were only teenagers again — all bruised knuckles and shining eyes, with the night open and forgiving around them.

Between one dawn and the next, Sevessa found time to send a reply to Lucius.
It was brief. Safe.
A single paragraph to say she was alive, that the ritual had been successful, that she was fine. She told him nothing more. He hadn’t written back. The silence sat heavy some nights, but she didn’t reach for it. Not yet.

Weekends softened around the edges.
They spent the mornings wandering through the green depths of Potter Wood, sunlight slipping between the trees. Cal led with reckless glee, Jem trailing behind shouting half-hearted warnings. Lily collected flowers she never quite remembered to press, while Peter and Remus argued quietly over paths. Sometimes James walked beside Sevessa, hands in his pockets, the silence between them easy.

Afternoons brought Quidditch — though Tobias had insisted the games include the Muggles, and that meant “creative adjustments.” They played with one team in the air and one on the ground, swapping roles every round. It was chaotic, loud, and completely unfair.

Then came the soccer matches.
Those were less friendly.
Lily, it turned out, hadn’t lost her edge. Within minutes she was weaving through them like lightning, sending Sirius sprawling and Peter yelping as another ball whizzed past. “This isn’t fair!” James had shouted once, chest heaving, sweat sticking his hair to his forehead. Lily only grinned, tapping the ball against her foot. “Don’t start a match you can’t finish, Potter.”

Sundays slowed. They filled with parchment, ink, and the scratch of quills. Sometimes they worked in companionable silence, sprawled across the manor’s library floor. Other times, they brewed.

The Animagus project.
That had been a shock.
A few days after the werewolf revelation, the other boys — sheepish, proud, and cornered — had admitted their secret. They’d done it. Illegally. They were Animagi.
James, Sirius, and Peter.
Three animals bound to one wolf.

They’d been gathered in the sitting room, sprawled across every available surface — books open, snacks half-eaten, conversation meandering between Quidditch scores and essay deadlines — when Sirius began to twitch.

At first it was subtle. A bounce of his knee. A drum of his fingers on the armrest. Then he huffed, crossed his arms, uncrossed them, and finally shot upright as though propelled by lightning.

“ARGH!” he exploded, startling Peter so badly he dropped his quill. “I’m an Animagus! I can’t take it anymore!”

The room froze.

“I’ve tried so hard to hold it in,” Sirius continued, pacing like a man confessing under duress. “But I can’t. Merlin knows I can’t hold it in! Everyone knows about Remus now and I figure—” he jabbed an accusing finger in Sevessa’s direction, “—you would’ve said something by now if you did know about us, but you haven’t! And now I can’t tell if it’s still a secret or not, and it is killing me! Genuinely, eating me alive from the inside. I am dying!”

“Pads,” James said weakly, pinching the bridge of his nose. “You are so unbelievably dramatic.”

“Well, someone had to tell her!” Sirius shot back, still mid-stride. “I’ve been walking around like a ticking confession bomb for weeks!”

Remus let out a long-suffering sigh. “You lasted all of four days.”

“That’s four more than I thought I’d manage!” Sirius said proudly.

There was a long pause. Then Cal, wide-eyed, leaned forward. “I’m sorry—what?”

“Animagus,” Sirius said, pointing to himself with a flourish. “Dog. Big one. Gorgeous fur.” He turned, pointing at the others in quick succession. “Stag, rat.”

Peter groaned. “Thanks, Pads, just—just tell everyone why don’t you?”

“Already did!” Sirius announced triumphantly, throwing himself back into the armchair like a conquering hero.

Lily blinked several times in rapid succession. “You three are illegal shape-shifters?”

“Illegal’s such a harsh word,” James said, though he was smiling faintly. “Let’s call it… independent magical research.”

Sevessa tilted her head, eyes glinting. “And this was all to help Remus, I presume?”

Remus nodded, resigned. “Early this year. They decided I shouldn’t be alone on full moons. So, they did it. Idiots, the lot of them—but loyal idiots.”

Sirius beamed. “The best kind.”

“Right,” Cal said slowly, “so… dog, rat, stag, and wolf.” He looked thoughtful. “Sounds like the beginning of a very weird joke.”

Sevessa couldn’t help the quiet laugh that slipped out. “Don’t give them ideas.”

“Oh, it’s far too late for that,” Remus said.

 

Laughter lingered like smoke long after the conversation had burned itself out.
Sirius was still grinning, Peter was blushing, and James looked far too pleased with himself for anyone’s comfort. Even Remus had that small, weary smile that meant he was pretending not to be touched. The room had softened around the edges — no tension, no wary silences, just the easy warmth of shared mischief.

Sevessa had retreated to the window seat by then, one knee tucked to her chest, chin propped on it. Outside, Potter Wood shimmered silver under the moonlight. The laughter faded into a low hum, like an afterglow, and she found herself watching the reflection of the others in the glass.

Loyal idiots, Remus had called them.
She couldn’t quite bring herself to disagree.

Lily drifted over, dropping onto the cushion beside her with a sigh that was half amusement, half awe. “They’re impossible,” she murmured. “Brilliant, but impossible.”

“Mm.” Sevessa’s lips quirked. “Brilliantly impossible.”

For a long while, neither spoke. The fire popped quietly behind them; outside, an owl called from somewhere deep in the trees. James and Sirius were arguing good-naturedly about whose transformation was more impressive (“Antlers are not practical, Prongs!” “Neither is drooling on the furniture, Padfoot!”), and Remus was too tired to intervene.

Lily tilted her head, studying Sevessa’s expression. “You’re thinking something,” she said quietly.

“I’m always thinking something.”

“Something reckless,” Lily countered. “Your eyebrow’s doing that twitch again.”

That earned her a soft, guilty smile. “Fine,” Sevessa admitted. “I’m thinking… if they can do it—”

Lily groaned, already catching on. “No. No, absolutely not.”

“—then why can’t we?” Sevessa finished, calm as ever.

“Because it’s illegal, Sev. And incredibly complicated.”

“So is half the stuff they get away with before breakfast.” Sevessa’s eyes gleamed. “Besides, we’ve got brains. Better brains. And patience.”

Lily opened her mouth to argue, then closed it again. Her gaze wandered over to the boys — Sirius still mid-rant, Peter half-asleep, James balancing a biscuit on his nose, and Remus looking every inch the exhausted parent of three disaster children.

A slow, conspiratorial smile curved her lips. “You’re serious.”

“No,” Sevessa said, deadpan, “he’s Sirius.”

Lily’s eyes narrowed, not in anger but in thought. The kind of sharp, calculating thought that always meant she was about to stop arguing and start planning.
“You’ve already found the potion, haven’t you?”

“Of course I have.” Sevessa’s smile tilted, faintly smug. “It’s half-buried in an old registry text from the 1800s. They used aconite instead of mandrake essence, which explains the unnecessary high accident rate.”

“Of course you have,” Lily muttered. She exhaled through her nose, long and slow, eyes dropping to the moonlit floor. “You realise if Tobias finds out, he’ll have an aneurysm.”

“He won’t.”

“He will.”

“Then we’d better not get caught.”

Lily stared at her for a long moment — and then, slowly, inevitably, the corner of her mouth twitched upward. “You’re insufferable.”

“Probably.”

“Fine,” Lily said at last, drawing herself up like a general committing to battle. “If we’re doing this, we’re doing it properly. I’m not dying because you read the instructions upside down.”

“Deal.”

They turned together — two sharp smiles, identical in their mischief — and faced the boys.

“Hey,” Sevessa called lightly.
Six heads turned.

“Where can we find two mandrake leaves in this Manor?”

 

Now, each weekend, they disappeared into the quiet corner of Sevessa’s bedroom, where an old cauldron simmered beneath a soft disillusion charm and their notes sprawled across the floor. Lily measured ingredients with surgeon’s precision; Sevessa stirred tirelessly when the recipe called for it. Together, they worked in rhythm — patient, methodical, and certain.

And when the potion shimmered faintly gold under the candlelight, both girls leaned close, faces reflected side by side in the surface. Lily smiled first, small and fierce. Sevessa’s came after — slower, steadier, satisfied.

The potion was ready.

It would hold for a month under stasis, though neither of them wanted to wait that long. As luck — or fate — would have it, a lightning storm was forecast for Thursday afternoon. The final ingredient, the spark that would awaken the magic, was already on its way.

The days that followed crawled and flew all at once.
They oscillated between distraction, anxiety, and bursts of laughter that bordered on hysteria. The mandrake leaves, tiny and unassuming, became constant companions — to be kept beneath the tongue, untouched, for the full lunar cycle.

Lily had nearly ruined everything two weeks in. She’d taken a long gulp of water at dinner, forgotten herself, and almost swallowed the leaf whole. Her eyes had gone wide as saucers; she’d bolted from the table coughing so violently Euphemia had called after her in alarm. The sound of retching and muffled swearing from the bathroom had reassured everyone she’d live — though not, perhaps, with dignity intact.

Sevessa hadn’t fared much better. Singing at Sullivan’s with her tongue half-paralysed had been an exercise in creative deception. Walter had squinted at her that first night, frowning at the rasp in her voice.

“Cold?” he’d asked.

“Something like that,” she’d managed.

He’d clapped her shoulder sympathetically and told her to drink honey tea. She’d done so. Through gritted teeth.

By the time Thursday arrived, the strain had worn thin. Both girls were jittery — sleep-deprived, restless, and oddly exhilarated.

When the first cracks of thunder rolled across the valley, they slipped out of the manor and into the trees.
The night was a living thing — wind moving through the leaves, rain spitting lightly against the ground, the sky a roiling sheet of cloud and lightning. The others followed at a distance, anxious.

They stopped in the clearing where the grass grew long and silvered under flashes of light.
The air was heavy, thick with ozone. The cauldron sat at the centre, its contents gleaming softly like molten sunlight.

Lily exhaled, fogging the air. “If we die,” she said, “I’m haunting you.”

“Then at least I’ll never be bored again,” Sevessa replied, voice steady but threaded with nerves.

The boys all stood off to the side, silent.

Sevessa met Lily’s eyes and took a deep breath.

They each filled a goblet, the potion swirling with slow, deliberate light. The forest seemed to still — even the rain paused between heartbeats.

“To new magic,” Sevessa murmured.

“To terrible ideas,” Lily answered, and they drank.

“Amato Animo Animato Animagus”

The effect was immediate.
Heat bloomed under their skin, sharp and searing, threading through muscle and bone. Lily gasped, dropping her goblet as her fingers spasmed; Sevessa dropped to her knees, fingers digging into the earth, breath shuddering out of her. The world pulsed, edges melting into light and sound — thunder in her ears, lightning in her chest.

It was agony. It was freedom.

Her vision split — one moment her own, the next a thousand shards of sensation: wind, scent, sound. The pounding of her own heart roared in her head like drums. Magic flooded her veins, ancient and unrelenting, reshaping what it touched.

Lily’s voice broke through, strangled and breathless. “Sev—Sevessa—!”

“I’m fine,” she gasped, though the word came out warped. Her tongue felt wrong — her body, wrong and right all at once. Her skin burned, her bones stretched, her breath came ragged — and then, suddenly, she was falling inward.

The floor met her with a strange softness. The air felt different. Sharper. Fuller.
And the world… smelled.

Where Sevessa and Lily had fallen, two creatures now stood in their wake.

The first — a doe, black as midnight, her coat catching every glimmer of lightning and turning it to glass. Her eyes gleamed dark gold, intelligent and calm, reflecting every spark of magic that had touched her.

The second — a tall mare, pale chestnut with an auburn mane, steam rising from her flank, breath misting in the air. She pawed the earth once, testing her strength, muscles shifting under rain-slicked skin.

The boys didn’t move. None of them could.

James’s throat worked silently, eyes wide and full of something close to awe.
Remus, quiet and steady, whispered, “Beautiful.”

The doe turned first — Sevessa’s familiar composure, quiet and sharp. Her head lifted, proud, alert. The horse beside her snorted, stamping softly, and leaned close — brushing Sevessa’s shoulder in a wordless question.

The black doe nuzzled back.

It was working. They were whole.

Then, in one sudden flash of joy, they ran.

The horse thundered forward first, hooves kicking up earth and silver spray. The doe followed, swift and sure, darting between trunks, her dark form cutting through the flashes of light like shadow given life. Rain lashed down as they moved, but neither slowed. The forest seemed to bow around them — the storm, the wind, the lightning — all alive, all pulsing with them.

Sirius whooped aloud, laughter swallowed by the thunder.
“Look at them go!”

Jem smiled — quiet, reverent. “That,” he said softly, “is awesome.”

James didn’t speak. His eyes were fixed on Sevessa, her movement effortless, powerful, wild.

He felt something deep and unshakable stir in his chest — the same rush of awe he’d felt when she’d first sung, only deeper now, bone-deep, like recognition.

The two shapes slowed at the far end of the clearing, circled once, and came back toward them — breath steaming, eyes bright. And as they stepped beneath the last fading streak of lightning, the glow began to dissolve.

Two girls stood where the creatures had been, barefoot in the wet grass, soaked and radiant.
Lily was laughing — breathless, incredulous. Sevessa just stood there for a moment, hair plastered to her face, eyes gleaming like liquid amber.

“Well,” Lily managed between gasps. “That was… horrifying.”

“And magnificent,” Sevessa added.

“Bloody terrifying,” Sirius said. “Do it again.”

She shot him a look, and for once, even he grinned sheepishly.

They stood together as the rain eased into a gentle patter, the storm finally passing beyond the ridge. The air smelled of pine and magic and something new — something like victory.

No one said the word, but they all felt it:
They’d done the impossible. Again.

And as the first hint of dawn slipped through the thinning clouds, Sevessa lifted her head toward the light, eyes dark and alive.
The black doe still lingered in her shadow, patient and sure.

Notes:

HIYA! What'd you think?

I love a little flashback moment, and I thought this story was moving a bit slowly in terms of the actual timeline, so we've got a small time jump here.

Also!! Lily is a horse! I considered a fox, I did, I really did, but then I was like "nahhhhh, lemme give her something cool! and Unique!"

Sevessa is a doe (Obvi), It's a cliché, I know, I warned you all at the top, but it's just so satisfying!!!!

Anyway, I'd love to know what you think of this chapter, especially of Lily being a horse. I just feel like it suits her so well. Fiercely loyal, protective, strong, graceful and gentle creatures, it just screamed LILY to me. Also, I desperately want Lily to exist as more than just 'James forgotten soulmate' in this story. I want her character to be independent of everyone else's, to really develop her sense of self. So, I'd also love feedback on how you think I'm going at that, for lily and also for the other characters. Do they feel unique and individual, or are they all blending together?

Love you all! Have a great week, and I'll see you on the 19/10!!
Byeeee
