IIRC, in the beginning of the episode stalker chick had been stalking the murder victim, and when she found out that he had been killed she transferred her attention to Booth. I don’t know if that would be a common action of a stalker-type personality, but I agree that it was a rather obvious set-up for that final scene.
Gormagone!
Do you mean the one played by Stephen Fry? I think we’d have heard if he were coming back for another guest appearance.
I wonder if they would be able to tell when Gormy had the teeth in the bomb removed – days before, or months or more before? I could imagine a scenario where Gormy could have had all his teeth removed and replaced by implants in order to throw off the investigation – though I’d think the shrapnel teeth would have some DNA in them for analysis.
