Personally... I love the scene where they are standing outside the diner and she's said that she's the sort of person that doesnt get to be part of a family and starts to cry. He tells her there are different sorts of families.. he holds her chin and stares straight into her eyes...he's trying to tell her that he's her family... god its so touching... I have lots of other favorite scenes, but I always seem to think about this one.
i think when Booth Saved her from that car - it was just so sweet - it was not even much of sign - but he new that little pop was Bones - an i just loved that he draged her out - then he just holded her ♥♥♥♥♥
I don't have just one favorite Booth/Bones moment, but one of them is (I'm not sure if this counts as a "Booth and Bones moment") at the end of Bullet in the Brain when Booth is watching Bones from inside the Royal Diner and, for the first time since he got back from Iraq, it is clear that he is in quite a predicament because he is in love with two women.
