Work Text:
Spencer had learned that there were certain sounds in Aaron Hotchner’s house that meant comfort. The hum of the refrigerator late at night. The soft whir of the dishwasher after dinner. The faint thud of small feet running down the hallway in socks that never quite stayed on. He had not meant to learn those sounds. They had simply accumulated over the past few months, one overnight bag at a time.
He was at the kitchen table with a stack of case files he was pretending to read when Jack padded in, hair sticking up in the back like he had just rolled across his pillow and lost the fight. It was late afternoon, the light slanting gold through the windows. Aaron had left twenty minutes earlier to pick up dry cleaning and stop by the hardware store. He had kissed Spencer briefly in the doorway before leaving. Spencer could still feel it, a warm press that had lingered just long enough to be remembered.
Jack dragged a chair across the tile with a scrape that made Spencer wince.
"Hey, buddy," Spencer said, folding the file closed. "Everything okay?"
Jack climbed onto the chair and folded his hands on the table like he was about to negotiate a treaty. He stared at Spencer with the kind of intense concentration only seven year olds and profilers could manage.
"Uncle Spencer," he said carefully, "are you my dad now too?"
Spencer blinked.
There were questions he could answer without thinking. The average gestation period of a blue whale. The precise wording of Miranda rights in all fifty states. The likelihood of rain based on atmospheric pressure. This was not one of those questions.
"I’m sorry?" Spencer asked, buying time.
Jack did not look uncertain. He looked patient. "Are you my other dad? Because you’re here a lot. And you tell me to eat broccoli. And you went to my soccer game. And you read the dragon book three times even though you said it was re-petitive."
Spencer’s mouth opened and then closed again. He could feel his pulse climbing, which was ridiculous. He had faced down armed suspects. He had been held at gunpoint more times than he wanted to remember. And yet this felt more dangerous, somehow.
"I… well," he began.
Jack leaned forward. "And you kiss my dad."
Spencer choked on air.
It was not loud, dramatic coughing. It was a small, contained disaster, the kind that burned behind the sternum. He reached for the glass of water Aaron had left behind and took a long sip.
Jack watched him, eyes wide but not alarmed. Curious.
"I’ve seen it twice," Jack added helpfully. "Once in the kitchen. And once when you thought I was watching cartoons."
Spencer closed his eyes briefly. Of course he had. Children missed very little, especially when it involved changes in their world.
When he opened them again, Jack was still there, chin propped in his hands.
"Well," Spencer said slowly, "sometimes adults kiss because they care about each other."
"I know that," Jack said. "If you kiss, you love each other. And if you love each other, you get married. That’s how it works."
Spencer pressed his lips together. The logic was airtight in the way only childhood logic could be.
He remembered being seven. He remembered wanting the world to be predictable. If A then B. If B then C. It had been comforting to believe that actions had clean consequences. It had taken years to unlearn that.
"Jack," he said gently, "it’s a little more complicated than that."
Jack frowned. "Why?"
Because life is complicated, Spencer thought. Because love is not a straight line. Because your father and I are still figuring out what this is and how it fits into a life that has already survived too much.
Aloud he said, "Kissing can mean a lot of things. Sometimes it means people care about each other very much. Sometimes it means they’re still deciding what that care looks like."
Jack considered that. "So you’re deciding?"
Spencer felt a warmth in his chest that had nothing to do with embarrassment. Aaron’s face flickered through his mind. The quiet steadiness of him. The way his hand had rested at the small of Spencer’s back that morning as they stood at the sink. The way he had smiled, soft and unguarded, when Jack had insisted Spencer help with a puzzle last night.
"Yes," Spencer said softly. "We’re deciding."
Jack nodded slowly, absorbing this like new vocabulary.
"But you stay here a lot," Jack pressed. "You have your toothbrush here. And you bought cereal I like, not the healthy one. And you come to soccer even when it’s cold."
Spencer could not help the small smile that tugged at his mouth. "Well, statistically speaking, emotional support during childhood extracurricular activities correlates with higher self esteem and long term resilience."
Jack blinked at him.
Spencer cleared his throat. "I like being there," he translated.
There was a silence that was not uncomfortable. The refrigerator hummed. A car passed outside. Somewhere down the block, a dog barked.
"Are you going to marry my dad?" Jack asked finally.
The question landed gently this time, less like a trap and more like an offering.
Spencer let himself imagine it for a second. Not the ceremony or the paperwork, but the feeling. The permanence. He imagined staying. He imagined this kitchen still being familiar years from now. He imagined Jack taller, voice deeper, still arguing about vegetables.
His chest tightened with something fragile and hopeful.
"I don’t know," he admitted. "That’s a really big decision. And it’s one your dad and I would make together."
Jack tilted his head. "But you love him."
It was not a question.
Spencer felt his face grow warm. He had not said those words out loud yet. They had existed in looks and touches and quiet moments, but saying them to a child felt monumental.
"Yes," he said, and the word settled in the room like it belonged there. "I do."
Jack’s expression softened in a way that startled Spencer. It was so much like Aaron’s when he was pleased but trying not to show it too much.
"Okay," Jack said.
"Okay?" Spencer echoed.
"Yeah." Jack shrugged. "That’s good."
Spencer laughed softly, tension easing from his shoulders. "You think so?"
"Yeah. Because my dad looks happy when you’re here." Jack picked at a small scratch in the table. "He doesn’t look sad like he used to sometimes."
The words were simple. They hit harder than any complicated analysis could have.
Spencer swallowed. He knew about the sad. He had seen it in the quiet evenings when Aaron thought no one was looking. He had seen it in the way Aaron held himself a little too rigid, like grief might knock him off balance if he relaxed.
"I’m glad," Spencer said quietly.
Jack studied him again. "So are you my other dad?"
Spencer exhaled slowly.
"I’m not trying to replace anyone," he said carefully. "You already have a dad. And you had a mom who loved you very much."
Jack nodded solemnly.
"But," Spencer continued, "I care about you. A lot. And I want to be someone you can count on. If that feels like another kind of dad to you, then… I’d be honored."
Jack’s eyes lit up in a way that made Spencer’s heart ache.
"So I can tell people you’re my other dad?"
Spencer hesitated only a second. "If that’s what you want."
Jack grinned, sudden and bright. "Okay."
He slid off the chair and darted around the table, wrapping his arms around Spencer’s waist without warning. Spencer stiffened for a fraction of a second, startled, then melted into it. He rested a hand carefully on the back of Jack’s head, fingers tangling in soft hair.
"I like when you read," Jack mumbled into his sweater. "Even if you use big words."
Spencer smiled against the top of his head. "I’ll try to limit the polysyllabic vocabulary."
Jack pulled back. "The what?"
"Big words," Spencer corrected.
"Good."
They separated just as the front door clicked open.
"Hey," Aaron called from the hallway. "I’m back. They didn’t have the exact screws I needed, so I had to improvise."
Spencer’s stomach flipped. He glanced at Jack, who looked entirely unbothered.
"In the kitchen," Jack called back.
Aaron stepped into view, coat still on, keys in hand. His gaze flicked between them, assessing as always. "Everything okay?"
Spencer felt a dozen possible explanations crowd his mind. None of them seemed adequate.
Jack beat him to it.
"Dad," he announced proudly, "I asked Uncle Spencer if he’s my other dad now. He said kind of. And that he loves you."
The silence that followed was thick but not sharp.
Aaron looked at Spencer.
Spencer felt heat crawl up his neck. He had been shot at and remained calmer.
"I was going to tell you," he muttered weakly.
Aaron’s lips twitched. He set the keys down slowly, as if approaching a skittish animal.
"You were, huh?" he said.
Spencer met his eyes. There was no anger there. Just surprise, and something warmer beneath it.
Jack looked between them, expectant.
Aaron stepped closer, resting a hand on Jack’s shoulder. "And how do you feel about that?"
Jack shrugged in exaggerated nonchalance. "It’s good. If you kiss someone you love them. And if you love them, you might get married. So I just wanted to check."
Aaron let out a quiet breath that might have been a laugh. He looked at Spencer again, and this time there was no mistaking the softness in his expression.
"We’re still figuring things out," Aaron said gently to Jack. "But what matters is that we both care about you. Very much."
Jack nodded, satisfied.
"And," Aaron added, glancing at Spencer, "we care about each other."
Spencer felt that warmth bloom again, steady and sure.
Jack clapped his hands once. "Okay. Can we have pizza?"
Aaron laughed outright this time. "That’s quite a leap in subject."
"But it’s Friday," Jack argued.
Spencer leaned back against the counter, watching them. The light had shifted, turning everything honey colored. He felt suspended in it, in this ordinary, extraordinary moment.
"Pizza sounds statistically reasonable," he offered.
Aaron shook his head fondly. "You are not using statistics to justify pepperoni."
"It’s a valid data driven decision," Spencer insisted.
Jack giggled.
Aaron moved closer, close enough that their shoulders brushed. He lowered his voice just enough that it felt private. "You told him you love me."
Spencer swallowed, suddenly shy. "He’s very perceptive."
Aaron’s hand found his, fingers lacing together naturally. "So are you."
For a second, the world narrowed to that touch.
Jack groaned dramatically. "You’re going to kiss again, aren’t you?"
Aaron raised an eyebrow. "Is that a problem?"
Jack rolled his eyes with all the gravity of someone who had endured too much adult affection. "It’s just weird."
Spencer laughed, tension dissolving entirely.
Aaron leaned in anyway, brushing his lips to Spencer’s in a brief, gentle kiss. It was soft and certain and entirely unhurried.
When they pulled back, Jack was watching, but he was smiling.
Spencer realized, with a quiet certainty, that whatever they were deciding, whatever shape this would take, it was already something real.
