Seeley hadn't even left his apartment yet. It was pretty obvious he hadn't even really gotten settled in two steps before getting bitched at by Mike. Before his vacation, Booth might have taken it a little more personally. But he was trying to let it all slide. Plus, he'd gotten his stash from his secret santa, and a brand new hockey stick. Not just any hockey stick, a signed hockey stick. He was going to mount it on his wall. It was just that awesome. When he wasn't feeling a need to break his computer and deal with teenagers, he'd have to sign on and thank Parker. She'd obviously gone through a lot of trouble for him.
Then there was the autographed hockey puck from Lucky Luc. It was in a display case and everything, sitting on the center of his kitchen table so he could look at it closely. He wasn't ready to put it away. At least until he heard the meek sound of Kitty's voice in his living room. "In the kitchen." He stated in attempt to give her some space. He didn't want to smother. He didn't want to intrude, he was trying to keep some distance, but his distance had only ruined things further. God relationships were not his forte. Why had he even gone there?
He still wasn't sure what he had with Buffy, if it was real. Yet there he was apparently trying to 'Yoda' as Mike had put it two teenagers through a relationship hell hole. Fixing things on the internet was never a good idea, so he did the next best thing in his opinion. Provided Kitty with a distraction. And when she was within hugging distance he did so. He didn't try to tell her to stop crying, or that it didn't help. She was a girl, and a teenage girl at that. So he was just there, and would be a rock if she needed, and as long as she needed.
"He'll come around. " He had no idea what was going on in full detail, but the way Mike had been acting? Booth pinned most of her tears on him. He wasn't happy seeing her so upset, in that moment he almost wished he could do more, but the entire point of his vacation was him backing down. He tried the advice thing, it didn't work, and that was all he could do. They had to make their own choices and take their own chances in life. He couldn't do it for them.
