Jason Gideon:
We know there are four types of poisoners who target multiple victims.

Aaron Hotchner:
There's the true believer, the political terrorist/religious cult.

Derek Morgan:
There's the extortionist, product tamperer who holds a business hostage in exchange for money.

Elle Greenaway:
Or the prankster, usually a younger offender who doesn't mean any harm and it's basically just a big practical joke.

Aaron Hotchner:
And the avenger. Someone with a personal vendetta who choses poison as their weapon.

Jason Gideon:
So we need to find out as quickly as possible which type he is, 'cause with the exception of the prankster, all these types commonly test their poison on a small scale before carrying out a larger attack.

Derek Morgan:
Well, let's hope this was just a prank.
