The moment Morgan realized Dave was like a dad to him wasn't necessarily triggered by any one event but instead an accumulation of things. Derek could point out many different times in his life when he was reminded of the fact the Dave had stepped into a father role for him. Specifically though it hit him when Savannah had Hank and Rossi stopped by.

"I don't think Uncle Dave fits you Rossi," Derek told him as Dave held little Hank in his arms. Morgan and Savannah had been talking and both had thought this was a great idea.

"What do you mean? That's what all the kids call me," Dave told him with a furrowed brow, he seemed worried and almost hesitant. He had always been Uncle Dave to any kids that his team had, it had started with Jack and just gone from there.

"Well Hank's got an Uncle Spencer and an Aunt Penelope but you know what he doesn't have on my side?"

"What's that?" Rossi asked as he smiled down at the bundle in his arms. He looked just like his daddy and Dave couldn't be more proud of the man who stood a few feet away.

"He doesn't have a Grandpa Dave," Derek told him.

Savannah watched Dave start to tear up, it melted her heart and she had to admit she loved the idea when Derek had brought it up. She knew Dave was like a father figure to him and realized how much this meant to him. Now watching Dave's face she realized how much it meant to Rossi as well.

"Well I'd love to be Grandpa Dave," he told little Hank as his eyes never left the little boy. "Grandpa is gonna spoil you rotten young man."

"I expect nothing less," Savannah commented.

Rossi kissed the little boy on the head and just held him for a while as he slept. He wasn't just Uncle Dave now. No, he was Grandpa Dave as well and that made Rossi a very happy man indeed.

The next time Derek was reminded of this was one random afternoon, a few years later, when the team came over for a cookout.

"Grandpa!" Hank screamed as Rossi walked out on the porch. The little boy took off across the yard and propelled himself into Dave's arms.

"Hey there piccolo uomo," Dave smiled as he hugged the boy in his arms.

Everyone smiled and Derek laughed at his son's theatrics. You couldn't get that boy excited about anything but tell him grandpa's coming over and he loses it.

"You being good?" Dave asked him seriously and the head nod Hank gave combined with the serious look he returned had everyone cracking up.

"Grandpa, did you bring the cars?" Hank asked as he whispered conspiratorially in Rossi's ear.

"I did but you have to wait till after dinner to get them," Rossi told the young man.

"Okay! Grandpa, Henry and I are playing catch. Can you play too?" Hank asked as he looked up at him with excitement.

"Let me go say hi to everyone then I will definitely go play catch," Rossi told him as he set the boy on his feet.

"Pushover," Morgan not so quietly whispered.

"I heard that," Dave said and sent a mock glare to the man.

"I don't know what you're talking about," Derek said throwing his hands up in innocence.

"Right," Dave rolled his eyes not believing him for a second.

Not much longer and Rossi had a glove on, was kneeling on the ground and tossing a ball back and forth between Henry and Hank.

"I don't think we could've made a better decision when Hank was born," Savannah told Morgan.

"He's always been like a dad to me, it only made since he be grandpa to Hank," Derek told her.

"He spoils that boy rotten though," she told him with a smile.

"Well he did promise that he would when Hank was born."

"Very true," She said as they watched the boys play catch.

"Food's ready!" Hotch called as he and Spencer finished setting everything out.

"I call sitting by grandpa!" Hank called as he raced to the table.

"Fine but I call sitting with Uncle Spence!" Henry called after him as he too took off.

Rossi just laughed as Spencer and he watched the boys jump into their seats.

"I want to sit next to Uncle Dave too though!" Jack complained as he walked away from his dad.

"How about I sit between you boys," Rossi suggested as he made his way over to get food. "That way you can both sit next to me."

"Well I want to sit next to Auntie Pen," Michael told them as he plopped down next to Penelope at the table.

"Well I sure would love to sit next to you too," she said giving the little boy a squeeze before placing some food in front of him to eat.

"What no one wants to sit next to their parents? Harsh," J.J. joked as she got Henry his food.

"But we see you all the time, we don't see Uncle Dave or Uncle Spence or Auntie Pen all the time," Henry tried to explain.

"Yea, I don't see grandpa all the time," Hank agreed vigorously.

"Grandpa's a pushover, you see him at least twice a week," Derek told his son.

"But that's not all the time daddy," Hank argued.

"I guess you're right little man," Morgan conceded with a smile.

"Eat," Dave told both Jack and Hank.

Everyone watch in amusement as both boys mimicked everything Dave did. If Rossi took a bite of his burger, the boy took a bit of their food. If Dave took a drink of his wine, the boys took a drink of their juice boxes.

"Let me correct myself," Rossi said as he noticed everyone watching them. "When I said eat I meant everyone."

With a few final chuckles the team dug in and conversations resumed like nothing had even happened.
