Despite Leo's return, Piper can't accept her sisters' death and borrows Coop's ring to travel back in time to prevent the fight. She lands when mother Patty was still alive, but takes her advise to cheat at constituting the power of three with a third generation, grandma Penny. Dumain meanwhile gets Billie to do her own time traveling to save Christie and the Triad. After the battle is undone, adult Christopher and Wyatt arrive to demand the charmed ones' help to save their future with even more confusing time travel.

You find out exactly what happens to all of the Halliwells in the last few minutes of this series. They even have a tribute to Prue. At the very end, they show a little girl sitting on a chair reading the Book of Shadows. The front door is left open, and the little girl points her finger towards the door, and the door closes (clearly using telekinesis), which is nearly the same thing Prue does at the end of the pilot episode, and the exact same that she does at the end of Season 2.
