The Heavens Can Wait/Plot

Cole finds Patience and tells her that he knows she is Prue. She then asks if Phoebe sent him, but he says that he's there on behalf of her mother and Grams. Prue explains that she was never truly allowed to move on into the afterlife due to the prophecy of the Charmed Ones keeping her tied to her sisters. She reunited with her family and Andy in the afterlife thanks to the Angels of Destiny, but she was still stuck between life and death. She explained that she was the one who found Paige and made the new power of three, but that the prophecy was never meant for Paige, so they were never as strong as the original three and Prue still had a connection. So she left the afterlife and hid in the Astral plane, but that didn't work. So she found the body of a comatose witch and took over. Because of this she felt stronger, causing the other three to feel stronger too. But she then explained that if the four of them ever united it would cause the opposite effect to that of three of them, it would weaken them and cause cataclysmic effects. She then asked Cole to keep her secret.

Bailey helps Leo find out who made the sword and finds where the maker's descendant is. Piper and the sisters overhear his plan to visit the descendant and demand to come after Phoebe had a premonition that he would get into trouble. They get to the descendants fort to find huge metal doors and magical weapons inside which attack them. They then find the descendant and she tells them that the sword was made for the Elders. The Elders were initially more than just guides and were warriors against the demons, but then changed and hid the sword away after they changed to become only guardians.

Bailey runs in to see Paige with information that Sarah (Patience/Prue's magical student) has come into her powers. We then find that Rennek is controlling Bailey, as part of this plan to unite the four sisters.
