Dr. Curtis Williamson, who treated the fever of Piper, unsuccessfully insists in calling her for follow-up exams in the hospital. Actually he is researching the blood of the Halliweel sisters in three monkeys. When is accidentally pricked with a blended mixture of their bloods, he becomes insane and evil, killing criminals to steal their organs for donation. Meanwhile, Prue is assigned to photograph Phoebe's idol, the actor Evan Stone, and a paparazzi shots pictures of them, bringing the spots on Prue. Piper tries to establish rules for Leo while staying in her house.
"Astral Monkey" is a silly episode of "Charmed", where Dr. Curtis Williamson from "Awakened" returns totally obsessed, stressed and crazy. But the process of transformation of the dedicated professional in a mad scientist is absolutely shallow. The "ins and outs" of Leo in the Halliwell sisters is an absolute lack of respect, and I believe most of the problems could be solved if Leo rings the bell of the front door like any other guest. My vote is six.
Title (Brazil): "Três Macacos" ("Three Monkeys")
