Please request if you have a one shot idea, I'm still having writers block for this

y/n walked behind her boyfriend Spencer and her dad Rossi. She looked around the room as her dad talked to a woman.

"When was the last time you saw him?" y/n asked the woman as she glanced at Spencer who was looking at a boy named Sammy who was playing with a wooden train by a piano .

"On his 5th birthday," the woman answered as she watched Sammy.

Rossi looked at y/n who was watching Spencer and Sammy. Rossi took over the questioning as Sammy sat down on the piano seat.

"Sammy can I sit here?" Spencer kindly asked getting a nod. He sat down next to Sammy, and looked at y/n who was leaning on a wall smiling.

She had always had a soft spot for kids and adorable moments. y/n always wanted to have a child of her own one day, and she knew she wanted it to be with Spencer. They hadn't talked about kids together let alone marriage.

Spencer and y/n had been together for 3 years and were very happy together. They had lived together for 2 of those years in y/n's little 3 bedroom home. It had turned into though a 2 bedroom since her and Spencer had transformed one of the rooms into a small library/office space for the two of them.

Spencer turned his attention back to Sammy who was looking at the piano curiously. Spencer played a few notes which Sammy copied. y/n covered her mouth as she giggled at the cuteness that was happening in front of her eyes.

Spencer played a note, "can you play that one for yes and," he played a different note, "this one for no?"

Sammy played the note for yes making Spencer smile, "do you remember the night the man came and took your parents away?" He asked.

Sammy played the yes note before continuing to play other notes that formed a song. y/n stood up straight with a confused look.

Spencer looked at Sammy, "I don't know what you're saying, does that song mean something to you?" Sammy stopped playing and placed Spencer's hand on the piano before moving his hand and starting to play the notes.

Spencer copied his movements so they played in unison. y/n watched in awe as they played the notes. y/n softly smiled, "wow," she whispered. 'I want kids with this cinnamon bun,' she thought.

y/n ran into the BAU followed by Spencer. They were a gosh darn mess. Hair was a mess, their clothes were messy, and they looked horrible.

"Wow, what the heck happened to you two?" Derek asked as he looked at them handing a muffin to y/n.

y/n took it looking like she was a kicked puppy while Spencer looked ready to snap. "Alarm clock broke and we woke up 5 minutes before we had to leave," Spencer's eye twitch.

"Well this is a scene from Freaky Friday," Penelope said as she looked between the two. y/n walked over to her desk and sat down while Penelope fixed her hair.

"So you still wanna have kids, y/n?" Derek snickered thinking Spencer knew that y/n wanted kids.

Spencer looked at her and laughed lightly at what she said as a response to Derek, "maybe after Spencer and I get a new alarm clock," she sighed as she began filling out her paperwork.

"That's a great idea y/n but we'll talk about kids later," Spencer chuckled getting a blush and nod from y/n.

Derek clapped his hands as he laughed. Penelope snickered as she continued to be like a mom and finished up fixing y/n's hair.

Rossi came into the room and looked at the scene not even questioning it as he handed y/n a hot chocolate and Spencer a coffee. They thanked him getting a smile and a nod. Rossi walked over to Derek before hitting him upside the head.

"Sorry," Derek mumbled as he rubbed the back of his head.

"You better be," Rossi said in a serious voice before smiling with a laugh not really being serious.

y/n smiled at Spencer who smiled back, "I'm never going to let you live down the fact that you got so mad at an alarm clock," y/n laughed.

Spencer rolled his eyes, "ok kicked puppy," he chuckled. y/n's mouth dropped a little with a shocked look. Spencer laughed at the shocked look.
