Ep 20. Astral Monkey

In the Charmed season 2 episode 20 titled "Astral Monkey", the three Charmed Ones; Piper, Phoebe, and Paige, find themselves in a tough situation when a convicted killer escapes from prison and uses a spell to swap bodies with Leo, Piper's husband.

The episode starts with a guard on watch at a prison giving some food to a prisoner and, unknowingly, opens a can of worms. The prisoner, who has been sentenced to death row for murder, manages to collect some hairs from the guard's hairbrush, which he later uses as a part of a spell to swap bodies with Leo.

In a twist of fate, Leo gets trapped in the killer's body, while the killer finds himself in Leo's body, free to do as he wills. After the swap, Leo is now in prison, and the killer is Leo, playing his play. The situation is further complicated as no one, including Piper, can tell the difference between the two bodies.

While the Charmed Ones must tackle this confusing situation, Piper must find a way to get her husband back. Their determination leads to Phoebe and Paige working on a spell to reverse the body swap, while Piper works to get her real husband, Leo, out of prison before he is executed.

As the three sisters race against time, the real killer, now trapped in Leo's body, enjoys his newfound freedom and takes advantage of his situation to cause harm. The killer, now having access to Leo's powers, channels his energy to harm those who come in his way, leaving Piper and her sisters to take the hit.

In a thrilling turn of events, the sisters are forced to use all their skills to keep themselves, and innocents, safe. Their plan of action involves protecting Leo in prison, securing the Book of Shadows, and reversing the body swap spell before it's too late.

The episode features superb acting performances by cast members, with the storyline written and executed to perfection. The episode also provides a tantalizing insight into the multi-faceted powers of Leo, who must remain anonymous to avoid lighting up the whole prison with his powerful aura.

As the episode progresses, we witness a dramatic turn of events, as the killer has turned out to be a witch connected to the sisters by the Halliwell demon gene. The twist adds a new layer of entertainment, keeping the viewer hooked till the episode's end.
