Booth really kind of wanted to tell Parker not to leave, but it wasn't his place. She had her friends now, and he should be happy for her. It wasn't like they were an item or anything. So why did it make things so awkward that she was moving?
Truth be told he was more then a little uncomfortable with Hardison around, but he wasn't going to say that either. He didn't want to do anything to make things harder on the blond thief. Ironically. If this were a typical dimension and she were a typical thief, there may have been problems and things would have been different. But Booth knew better. Not only was crime not his department, they had bigger fish to fry and he was looking at the broad picture. Demons and the apocalypse and such.
He knew that some of Parker's team were unlikely to understand that message, but what mattered was he had friends like Eliot and Parker on his side even if the other didn't. Seeley was never good at goodbyes, but he didn't want her to go without at least giving her a hug or a handshake or..something. He ran a hand through his dark and short her as he made it down the stairs and into the lobby where he spotted her.
"Parker." He offered her a tiny smile and an attempt not to be weird. "Got everything?" He asked her as he walked closer to her and stood by her side.
