Working on Our 'S' Sound

"Papa! Papa!"

"Baby Boy!"

Derek Morgan bent his knees and scooped Matt up in his arms, smothering the toddler with kisses. Clooney barked at them and he heard Spencer in the background telling Clooney to sit. Matt clung to Derek and laughed at the chaos.

He shifted the boy to his hip to see Spencer standing in front of him, smiling. Derek took a step forward, wrapping his free arm around the genius's waist. "Hi."

"Hi, yourself." Spencer kissed him. "Ask Matt about his day."

"Matt, what did you do today?"

"Walk."

Spencer chuckled. "Around and around and around."

"He's big on circles," Derek bounced the toddler higher on his hip. "What else?"

"Dat Unca Jasssson."

"We perfected the 's' sound." Derek's brain caught up with the baby's statement. "Uncle Jason?"

The kitchen timer dinged and Spencer disentangled himself from Derek's grip. Derek followed his partner into the kitchen, bouncing Matt on his hip. "Spencer?"

Spencer pulled the chicken out of the oven and shut the door before turning to Derek. "Gideon showed up."

"Do I need to go after him?"

"No, but thank you for the offer." Spencer took Matt and buckled him into his high chair.

"Spencer."

Matt picked up his fork and banged it against the tray. Spencer straightened the turned to Derek. The dark man put his hands on the lithe man's hips. Spencer just smiled and shook his head. "You don't have to go after him. I have you."

"He should still be part of Matt's life."

"He'll be an uncle, just like Hotch and Rossi," Spencer draped his long arms around Derek's shoulders. "He'll send gifts and cards on birthdays and Christmas, more than my dad ever did, and he'll stop in when he's in the neighborhood."

"He's his son," Derek insisted.

"No, he's our son. Gideon just happens to share DNA with him." Spencer rested his forehead against Derek's. "It takes more than genetics to be a father."

"Any fool can be a Father, but it takes a real man to be a Daddy, I know."

"Philip Whitmore Senior."

"Dee! Papa!"

"One moment, Matt." Derek tipped his head to kiss Spencer. "You are amazing, you know that?"

"What have I done this time?"

"Nothing."

Amused, Spencer returned to the kitchen to plate dinner. Derek ruffled Matt's curls before getting out cups and pouring drinks. He hunted up Matt's sippy cup from the living room and rinsed it out. Standing over the sink, he chuckled.

"What?"

He glanced at Spencer. "Hotch is going to have a fit. He's been tracking Gideon."

"Why?"

Derek raised his eyebrow.

"For me? He didn't have to do that."

"We're family, Spencer. We look out for each other."

"DEE!"

Spencer grabbed the fork from Matt's hand before it flew across the table.

"You're getting good at that."

"His aim is getting better," Spencer shook his head. "He did not get that from me."

"I'll say," Derek handed the toddler the sippy cup with juice and sat down. Spencer cut up Matt's chicken and offered a forkful to him. Matt took the bite and chewed, watching the two men. Spencer ate with his other hand, waiting for Matt to finish his first bite.

"Don't even think about it, Matthew," Spencer warned as the toddler leaned over the side of his high chair. "If you spit that out, you're getting baby food."

Matt pulled back and swallowed. He lifted his sippy cup, ignoring the fork that Spencer offered.

Derek smothered a laugh. "Well, that he got from you."

Spencer glared at Derek and Matt used that moment to steal back the fork and chomp down on the chicken.

"Hey, Spencer?"

"Yes."

"Want another one?"

Matt threw the third piece of chicken on the floor; Clooney pounced on it.

Spencer sighed and took the fork away. "Can we wait until he's a bit older?"

Derek glanced at Matt, now angrily sucking away at the sippy cup. "Yeah, two might be a bit much."

"We should find out if you're a carrier."

Derek choked on his water.
