One more thing - the end with B&B and Sweets' observation. Either i'm dense or....I couldn't figure out which one it is that's struggling with the attraction. Booth was surprised and a little out of his element when she was putting the kerchief back, you could see it in his face, but the expression on hers was very tender. Argggg. Which is it?! Don't we get a double-dose again next week?
I couldn't figure it out either! Perhaps we weren't supposed to be able to tell. Maybe it will be picked up again in a later episode. When I first saw it, however, I thought they were implying it was Bones. But after I rewatched that scene several times, I decided that it was Booth. There was nothing that strange about Brennan putting the kerchief back into Booth's pocket. In fact it's something she would do. But Booth's reaction was like...wow, she just touched me. I'm still not sure though. I hope it's clarified later on.
Of course Booth wants her. I think that's been obvious for a while. So yeah, I think he deals with it every day. The thing is... I think Brennan deals with her attraction to Booth every day too, and that's a problem for her. It's more of an actual struggle for her, and this is why I think that is:
She's getting more and more emotional as time goes on, and I think it scares her. What probably scares her most is that she's been attracted to Booth consistently for years and such consistency contradicts her understanding of anthropological fact, that humans are not monogamous by nature. If the facts of reality are being challenged by her own emotions, well, we might as well assume that she's going through a personal crisis.
That's my theory, and if I'm proven wrong, well... at least I can say that I had a rational basis for my idea.
