Harbinger in the fountain! May be a spoiler alert!

I personally don't think the MRI scene was lame or that Sweets really screwed up, because In my opinion the scans are technically correct, but Sweets misunderstood them. What I mean is, I think Booth did already love her, but he wasn't in a rush to tell her was he? Then all of a sudden he wants to tell her after the op? I think his brain still isn't back to normal and it's making him more focused on the love, more aware of it and that's why the scans look different, and why he suddenly wanted to tell Brennan, but I do think the love was already there. The scans look different because the problems with his brain made the love (well, the chemical reactions a brain has to love) more prominent. Even though I don't think the love is fake or a symptom I do think the fact that he is all of a sudden ready to tell Brennan is a symptom.

It's better that Sweets pointed it out, otherwise Brennan might not believe Booth (she is so logical if he says he loves her so soon after a brain op she would not believe him) so Sweets did the right thing. When Booth still feels the love even after the symptoms are gone it will prove the love is real, and make it more likely that Brennan will believe it and accept it.

I think that Sweets sux and that the MRI scene was pretty lame xD

Yeah I didn't like that he said it either! It made Booth question his feelings - the feelings we --and Sweets-- knew he had before but just didn't act on - but I think that Avalon set the balance back with what she said and made Booth belive they were true agian! ;D
