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.
