This was a great/scary episode because it felt like something that could actually happen without much effort involved. Some whacko is dosing the general public with huge amounts of LSD and Rohypnol (the date rape drug). That's not exactly a great combination because the LSD makes you hallucinate and the roofies make you forget about all the crazy stuff you did while hallucinating. So the question becomes where did seven different and unrelated people all come in contact with these two drugs?

Of the seven that had been poisoned, two had died and one of them (a father) nearly beat his own son to death. Yet he had no recollection of doing it. Not ideal for Gideon and the BAU team.

Oh, and another nice bit of news: according to Cynopsis, Kirsten Vangsness (who plays Garcia) has been added as a series regular now. I assume this means we can expect the show open to change soon.

So there's a nut who likes to poison people. But Elle is quick to remind us uninformed viewers (I love how the show does this) that this guy was probably only running a test here and his actual target had not been hit yet. Gideon is fairly convinced that when he hits again, LSD and roofies won't be his poison of choice. Then a woman shows up at the hospital and she's diagnosed with botulism. But they recognize her. She was the same woman that the team saw on surveillance footage at a bank that all the other initial seven victims had been at.

She dies, but the team ties her to a local pharmaceutical company. Gideon reasons that it's unlikely she dosed herself, so she must have been doing someone else's dirty work and then she got the axe. They examine the bank and test everything. The source of the poison was in the lick-strip on the bank envelopes. Garcia pulls up some records from the pharmaceutical company and they find some disgruntled guy who lost out on a patent to them a few months back. Plus he knew the dead woman. Bingo. His intended target was actually the executives at the company and the BAU team catches up to them at some company retreat in time to give them the botulism anti-toxin.

Stuff like this freaks me out though. After all the "anthrax in the mail" scares from a few years back I don't know if I like the idea of this episode airing and putting new ideas in the heads of certain people.
