Deja Vu All Over Again

The beginning of this epochal episode has Phoebe experiencing a powerful and deadly premonition of death at Halliwell manor which includes Inspector Rodriguez unmasked in a demon attack on the sisters resulting in the killing of Prue's childhood friend and sometimes love interest, Andy Trudeau. Vowing to prevent Andy's death, Prue heads off to police headquarters to warn Andy that Rodriguez is a double-agent, a demon working undercover for evil's causes. As the demon makes plans for his attempt to kill the Charmed Ones, he receives a visit from Tempus, a demon who can turn back time that was sent by the source to help Inspector Rodriguez should he fail. Tempus will rewind time each time Rodriguez fails to kill the Charmed Ones until the warlock succeeds in killing all the sisters. Andy Trudeau is waiting in his car, after being told by Prue to stay away because it was dangerous. He sees Rodriguez entering the house and goes in to protect Prue. Andy bursts in before Rodriguez can harm the sisters and attempts to shoot him, but Rodriguez fires an energy ball at Andy, killing him. Piper freezes Rodriguez and she and Phoebe are shocked to find Andy dead. Prue receives a vision from the spirit of the now deceased Andy, which helps her to move on. The sisters vanquish Rodriguez and attend Andy's funeral.
