Bones, Season 5

Sweets:
Do you know what you're looking at?

Booth:
Yeah, and I'm pretty sure you haven't been this close to one in a long time.

Sweets:
It's a PET scan of your brain.

Booth:
Hmm. Then I was wrong.

Sweets:
This is called the ventral tegmental area, and this is the dorsal caudate body. Now these two areas have been proven to be linked to romantic love and sexual arousal.

Booth:
Okay, if this is your version of dirty pictures, they're not working for me right now. [Closes the laptop computer.]

Sweets:
No. [Reopens computer] This, uh, this scan was taken before your operation. The green and blue colors indicate very low activity. The same scan while you were in the coma: lit up like the fourth of July. You were dreaming of being in love, of being married, right? [changes image] The same scan, three days ago. Before your operation you were not in love. After your operation you were. Conclusion: your feelings are not real and will fade away, like every other symptom of your coma. Now, I think you and I both know that Dr. Brennan's hyper-rationale is really just a cover for a very vulnerable and sensitive core.

Booth:
Oh, great. So we're talking about Bones' brain, too, here now.

Sweets:
So, if you breach those defenses and it turns out you don't really love her -- [puts PET scans on table] -- I left you hard copies.
