After the manor gets burglarized, Piper and Phoebe become concerned that Prue is becoming obsessed with learning everything about the Evil Triad sending demons to destroy them. When Darryl comes to investigate the break-in, he tries to convince Prue that it was the work of human thieves, but she's certain that the suspect is supernatural. Upon meeting with the Triad, Cole is upset that his bosses are sending another demon to try and destroy the Charmed Ones, despite his assurance he'll destroy them on his own. Meanwhile, Piper is certain that Leo's bosses are behind another ruined attempt of having a normal, romantic date.
