Phoenix Wright loaded with KO's

Ok I just finished another case in Phoenix Wright for the Nintendo DS. Man this game is full of references to people getting head KO'd, drugged and possibly even chloroformed? That's right, I have a strong suspicion that one case has a "subtle" chloroforming. This case has a cute girl getting put to sleep with a "sleeping agent". Okay, we really don't know what it is but I know it has to be chloroform. The circumstances basically mean that is the only possibility. The game doesn't describe what this sleeping agent is, but it has to be something that acts fast and chloroform seems to be the only option (in fiction at least). There's even a picture of the girl sleeping! I'm being purposely vague because I don't want to ruin the game for anyone. I am loving this game more and more.
