Meanwhile, back at Magic School, Billie prepares to project herself into the past. When Dumain mentions she has to focus on the time of the existence of The Triad, she suspects something is up and finally realizes she has been manipulated. Dumain tells her to go back in time and ask Christy, so she will understand. When Grams wakes up, Patty tells her that her daughters grow up to become The Charmed Ones, and immediately wants to help. Meanwhile, Billie projects herself to the manor, during the time past Billie and Christy arrive to battle with The Charmed Ones. When she tries to warn the two about what will happen, past Billie sends her flying into a wall. When the battle begins, the three-generation Power of Three—Grams, Patty and Piper—arrive to recite a spell to remove The Hollow from the past Charmed Ones and past Billie and Christy, thus stopping the battle and changing the future. Present Billie and Piper then merge into their past selves, and Billie and Christy teleport out of the manor because they no longer have the magic boosting aid of The Hollow. The Angel of Destiny (Denise Dowse) arrives to take Leo back again because the battle did not occur. The future Wyatt (Wes Ramsey) and Chris (Drew Fuller) appear in the manor, revealing that someone has messed with their future.
