When Phoebe's calls for Coop fail, future Wyatt and Chris reveal that Coop was sent by The Elders to make up for all the events they put her through as a Charmed One, and that it is not a forbidden love. They also explain that in the future all she has to do is think about Coop to summon him. He then appears in great pain and reveals that Dumain took his ring so he and Christy can travel back in time. While she realizes it's too late to stop them, Billie has the ability to time travel too. When present Dumain and Christy arrive in the past, they warn The Triad to convince past Christy and Billie to invoke The Hollow before The Charmed Ones. Present Billie and The Charmed Ones arrive a moment later thanks to Billie focusing on Christy to vanquish The Triad, and Piper blows up the past and present versions of Dumain, leaving Christy without any allies. When Billie begs Christy to come back to the good side, Christy is enraged and launches a fireball at her sister which Billie deflects with telekinesis, vaporizing Christy. Billie immediately collapses in tears while the sisters feel her pain. A family reunion then takes place in the sun room of the manor and Wyatt reveals that he has his powers back. The Angel of Destiny returns with Leo and reveals that this was how the battle was supposed to end. Patty also reveals that she now knows of Prue's death thanks to Victor, and she understands and accepts her death because of Paige's existence. Coop takes Grams, Patty, Chris and Wyatt back to their own times and erases their memories of the recent events.
