Part 2 of big shoes to fill
CHOSEN FAMILY
Spencer planned to pick you up at 5:30 p.m. He had gotten home pretty late last night from a case in California, so he went straight to his place, not wanting to wake you or Theo up.
You spent two hours getting ready, searching for the right outfit, doing your makeup, and styling your hair. You needed to look nice. It was the first time you were meeting Spencer's friends at one of their houses for a dinner night.
Eventually, you picked your favorite blue dress that flowed from your waist to your knees, with tiny daisies printed on it. You waved your hair and chose the special-occasion perfume you'd once received as a birthday gift.
"Mom..."
You looked in the mirror, meeting your son's worried eyes.
"What's up, Bug?" You smiled softly before turning to him and crouching down to his level."What if they don't like me?" he asked, playing with the hem of his shirt.
"You are an amazing, bright, and kind eight-year-old boy. Why wouldn't they like you?" you asked gently, taking his hands in yours and giving them a reassuring squeeze.
"Dad already doesn't like me," he mumbled.
That broke your heart in two.
You never had the best relationship with his dad, Evan, but you'd tried hard to maintain the relationship between Theo and him. Eventually, the contact became less and less frequent, fading away completely a year ago when he started "his proper family." Now it was just birthday cards in the mail and occasional child support around Christmas and the beginning of the school year.
Theo had a half-sister he didn't know existed because you didn't want to hurt him even more.
"I'm sure that's not true, baby," you said softly, wrapping him in a hug.
"I love you so, so much, Bug. And I know Spencer loves you too. That's important, right? And he loves his friends. Do you think he would be friends with people who wouldn't notice what an amazing young man you are?"
Theo thought about it for a moment.
"No," he said eventually, though you still saw the doubt in his eyes.
"Exactly. He wouldn't. So how about we get you dressed in a nice shirt, pick up the cookies we made after school, and wait for Spencer? He should be here any minute."
You glanced at the clock above the bathroom door.
"Okay."
Theo kissed your cheek before grabbing your hand and leading you to his room.
You let him pick his favorite baby-blue button-down shirt with a Pokémon pattern on it, dark jeans, and Converse sneakers before packing two trays of space-shaped cookies into a container. The two of you had gone overboard with rocket, star, planet, and moon shapes.
At exactly 5:30, a soft knock sounded at the door before Spencer let himself in.
"Hi, guys! You ready to go?" he called from the hallway as you appeared.
"Almost ready."
You hurried over to kiss him hello, smiling as you wrapped your arms around him.
"Theo had a hard moment," you said quietly. "He got scared your team won't like him. He said... he said they might not like him because his dad doesn't. I don't know what to do, Spence."
You rested your forehead against his chest and closed your eyes for a moment.
"You want me to talk to him?" he asked softly, resting his cheek on top of your head.
"No, no. It's not your job to raise him and solve all the dad-not-present-related drama. I got this. I just needed—"
He stopped you right there, tilting your head up so you could see him. There was care in his eyes and a soft, reassuring smile on his lips.
"Hey, baby, stop. I love you, and I love your son. And if you let me help raise him in any way, it would be my honor."
You exhaled a shaky breath before nodding once.
"Alright," you whispered, unable to break eye contact. "Thank you, Spencer. I love you too. And I'm sure he does too."
He squeezed your hips reassuringly before stepping back.
"I'm gonna talk to him, and then we can go. Will you take the cookies out to the car in the meantime?"
Spencer knocked on Theo's partially open door and peeked inside.
"Hey, buddy." He smiled softly as he walked into the room. "Can I sit with you?"
"Yeah."
Reid sat down beside him, casually brushing his arm against Theo's in reassurance.
"Your mom told me you were worried about meeting my friends," he began, watching as Theo bit his lip and looked down.
"I also know they'll be thrilled to meet you."
He reached over and wrapped his fingers around Theo's small hand.
"You sure?" Theo looked up at him, still worried. "I don't want them to dislike me, 'cause then you'd dislike me, and you'd leave, and I don't want you to leave like Dad."
Tears filled his eyes as the fear of being abandoned again tightened in his chest.
"Heeey, don't cry, T."
Spencer immediately knelt in front of him and gently stroked his cheek with his thumb.
"I'm not going to leave you, okay? Never. I love you too much to do that. I'd miss you too much."
His heart broke just as yours had a few moments earlier.
"And I know my friends will love you too. Because they're my family. And you're my family. You and your mama. Sometimes the family we choose is more important than the one we're born into. And that's okay.
"I know you miss your dad, but I also know it's his loss that he walked out of your life. Because he won't get the pleasure of watching you grow up and do amazing things. And I'm freaking grateful that you let me witness it."
Theo stared at him for a moment, unable to put his feelings into words.
Instead, he leaned forward and threw himself into Spencer's arms, burying his face in his shirt.
Reid hugged him tightly, one arm around his back and the other in his hair.
"I love you too," Theo whispered into Spencer's neck.
"I know, buddy."
You arrived at the huge Rossi house ten minutes late. Spencer had called ahead to warn everyone about Theo's worries.
Theo walked between you and Spencer, holding both your hands when the door opened to reveal a bright blonde woman.
"Here's the big guy I've heard so much about! And the beautiful woman! Oh my God, I'm so happy to meet you! This genius boy was so secretive about you two that I wasn't sure you actually existed!"
"Y/N, Theo, meet Penelope Garcia. Pen, this is my girlfriend, Y/N, and my boy, Theo."
You saw the spark in Theo's eyes when Spencer called him his.
Penelope hugged you tightly before crouching down to give Theo the same warm welcome.
The rest followed. Hugs were exchanged, and then everyone was ushered to the table.
"I love your shirt!" Michael grinned at Theo, his missing tooth and mischievous smile on full display.
"Thank you! It's Charmander, my favorite!"
The conversation was easy, the food was delicious, and when Spencer brought out the cookies you'd made, everyone was over the moon.
"Theo, you baked these?" JJ asked, smiling as your son sat with her two boys on the couch.
"Yes! I helped Mama shape and decorate them, and she let me mix the eggs!"
He sounded so proud that you couldn't help smiling.
You looked over at Spencer as the boys started talking about space because apparently every boy that age wanted to be an astronaut. He smiled back, wrapping an arm around you so you could lean against him and enjoy the easy, pleasant evening with the people who were his family.
You watched Theo holding Morgan's hand as they searched for the best board game to play and couldn't help smiling when he hesitantly asked if he could call him Uncle, like Spencer had suggested.
Derek's eyes lit up immediately.
"Of course you can!"
He picked Theo up because apparently hugging his new nephew was necessary to make the arrangement official.
You stood in the doorway leading to the patio, wine glass in hand, watching Spencer perform magic tricks for the boys.
You sensed someone approaching but couldn't take your eyes off them.
"You're good for him," JJ said softly as she stepped beside you, her own glass in hand.
"I don't know why, but I could tell he was happier these last few months. Calmer. Checking his phone more. Now I know why."
She smiled and rubbed your arm gently.
"And I'm happy he found someone steady in his life."
Then she added quietly, "Just please don't break his heart."
You shook your head.
"How could I purposely break his heart when it would mean destroying three hearts in the process?"
You looked back at the boys just as Theo launched himself into Spencer's arms, laughing loudly.
Later, the boys were asleep on the couch, a tangle of limbs and soft breaths, while a video game still blinked on the television.
You and JJ collected abandoned devices while Will picked Henry up, leaving JJ to carry the younger boy.
You bent down to lift Theo when you felt a warm hand on your back.
"I've got him."
Spencer smiled and kissed the top of your head, so you simply watched as he carefully lifted your son into his arms before saying quiet goodbyes to the team.
You helped him with the door and buckled Theo into his car seat before climbing into the passenger seat.
"Thank you for today," you said, looking over at Spencer.
He didn't reply immediately. Instead, he leaned over and kissed you sweetly.
"Thank you for being here with me today. It's nice to finally share them with you. They already love you and Theo."
You smiled.
"I love them too. Let's go home, Spence."
"Yeah," he said softly. "Home."
Then he started the car and turned toward your place.
