AOS: Something like Jim and Spock realize they are head over heels for Leonard when they see him with Joanna. This can be separate events or at the same time. Basically just Leonard being super cute with his daughter and Jim and Spock really digging it would be awesome!
"Daddy!" Bones scooped Joanna up into his arms.
"How's my little angel? Not causing you're mother any trouble are you?" Joanna glared at him and Jim chuckled. He hadn't meant to be watching them but they were right in the middle of the Academy's courtyard. "Let's get some ice cream."
"Yes!" Joanna punched the air.
Jim had heard Bones' complaints about his ex-wife but he had never really thought about Bones being a family man. Fatherhood suited him, he was lighter somehow, more approachable. Not that Bones wasn't already very approachable, as long as he wasn't holding a hyposhot. Jim's heart nearly stopped when Bones looked at him. He really hoped he was there the next time Joanna came to visit.
They walked up to him. "Jo, this is Jim. He's my roommate."
"Pleased to meet you Jo. Has Bones showed you around the campus yet?"
Jo nodded and Jim was surprised at how disappointed he was. He would have liked to see Bones explain everything to her, maybe walk along aside the two of them. "It's nice to meet you."
"We'll see you around," Bones said. Then he told Joanna to say "bye-bye."
"Bye-bye Mr Jim."
Jim waved as they walked off. He barely caught Bones saying "It's Mr Kirk."
He watched them as long as he could, quickly realizing he had it bad. This was the cutest Bones had ever been and here he was imaging them being domestic.
Spock watched Bones and Jo look at the window display of a toy store. He hadn't meant to stare but he had seen the side of Bones' face, enough to know that he really had seen Bones. Spock had no previous inkling that Bones was a father. There was no point in denying that they were cute together.
He wanted to go over to them but couldn't find the courage. I shouldn't bother them anyway. I barely know Dr McCoy and their time together may be rare.
Spock walked off quickly when they entered the store. He realized how much he wanted to get to know Bones.
