The episode title and all character references to monkeys are in error. The featured primates are chimpanzees, which are not monkeys. The key characteristic of monkeys is a tail, which chimpanzees lack. See more »


Evan Stone: You can't fight back. That's like struggling in quicksand. Don't play. Look, whatever energy they're throwing at you just pass right on by, because eventually that energy comes back around and leads to someone else.
Prue Halliwell: Yeah, uh, okay, I-I-I really appreciate the whole wax-on, wax-off approach, but couldn't your people just issue some kind of statement?

The Law of Unintended Consequenses

If you don't know what that is, you will after watching this episode. The doctor who treated Piper for aurora fever is obsessed with figuring out how she recovered, and is doing everything he can to figure it out in the hopes of curing more diseases. Unfortunately, when studying the sisters' blood, he is exposed to it, and it has some rather nasty side effects. This episode shows what happens when the sisters act without thought for what might happen down the road, and an innocent ends up paying the price. While the monkeys and Leo may inject a note of levity in this episode, it also shows what can happen when those with power aren't careful.
