Chapter Text
When a Shadowhunter child is born, they are born with a seed tattoo. When they meet their soulmate, the seed is said to bloom. Some of the elder Shadowhunters say its because Shadowhunters don’t usually live long so Raziel wanted them to be as happy as possible for as long as possible.
It’s said those with two seeds are destined to be Parabatai. The flower will always represent the people they were destined to be with. Studies about flowers are done along side runes, Alec is sure his flower is going to be a rose. New York is his home, even if he does return to Idris a lot. He’s proven right once he meets his foster brother, Jace Wayland. He watched in fascination as the seed on both their wrists crack open and two flowers on each wrist start to bloom. They immediately begin Parabatai training.
They train day in and day out to be able to do the Parabatai ceremony as soon as possible. After 8 years of training side by side and at age 16, they take the ceremony. The flowers on each others wrists in full bloom. Alec was right, he could see his Rose intertwined with Jace’s Brugmansia as he lifted his wrist. They were strong for such a young Parabatai pairing.
Alec fell for Jace even though he knew his Parabatai wasn’t his soulmate. He brushed it off as brotherly love or at the least familial love. But that didn’t explain why he woke up in cold sweats over Jace leaving him during the Parabatai ceremony for a young redhead.
The only person he told was Izzy. He trusted Izzy to keep a secret. She was smart for her age, even if a lot of people said she hadn’t yet grown into her looks. Alec thought she looked find as she was and fought anyone who said differently, including their mother.
“You’re supposed to wear dresses Isabelle! Not horrible jogging pants.”
“You’re never going to leave to walk in high heels if you refuse to!”
“No, you’re make up is all wrong, look at that smudge!”
Alec always got her out of the situations fast and that was how they ended up in this situation, sitting against one of the pillars in the training room, giggling quietly.
“Her face was hilarious.” Izzy giggled, “That won’t work again though.”
Alec shook his head in mock sadness, “Yeah, unfortunately.” They both sat in silence for a few minutes.
“Izzy?”
“Yeah?”
“I think I like Jace.”
“Of course you do, he’s your Parabatai!”
“No… I like like Jace.”
"Oh... Are you going to do anything about it?"
"I can't... Mom would flip."
"Are you still going to become his Parabatai?"
Alec lifted his wrist to show Izzy the two intertwined flowers, "I mean, it is fate."
"Alec, one day you'll find someone who loves you heart and soul." Izzy lifted her wrist to show him her seed, "We all will."
"... Do you ever think our soulmates could be Mundanes or Downworlders?"
"I mean... Its a possibility right? Even though they aren't born with seeds?" Izzy said, leaning her head back against the pillar.
"I don't know. I would be scared if it was."
"Why?"
"Because theres probably a reason we don't know the answer to that and thats the fact that the Clave doesn't like it."
Suddenly the door banged open, "Isabelle! Alexander!" Maryse called. Both children held their breath.
"Maryse?" came a young Jace's voice, "Want me to help find them?"
"Oh yes, please Jace. I'm going to check in the main room again. Seriously, sometimes those two are as bad as each other." She sounded more angry than joking.
The two hidden heard the door close. "Alec I know you're in here and I'm guessing Izzy is too. Maryse is gone but I don't know for how long for, I'll distract her for 10 minutes, get to the roof." At that the door opened and closed again and the last two Lightwood siblings let out of breath.
"To the roof it is then!" Alec said, pulling Izzy up with him, "Race you there!"
