Time Heals

Time Heals is the forty-first episode of Ben 10: Alien Force.

Plot
Gwen steals a book from Hex that allows her to travel back in time so she can stop the Omnitrix from overloading. Paradox intervenes just before the spell is activated, warning Gwen that the consequences for "fooling" with time are extremely severe. Gwen activates the spell anyway. She convinces her past self to stop Ben and Kevin from starting the machine that overloaded the Omnitrix. Her plan succeeds and she returns to the present where she finds a group of humans being held hostage by Charmcaster's minions (she enters into an alternate timeline). She attempts to fight them off, but is outnumbered and runs into Paradox. He tells Gwen that Kevin wasn't able to help fight off Hex and Charmcaster's forces because he didn't have his monstrous form's abilities and was turned into a monster minion. The alternate Gwen, however, was killed by Charmcaster. The current Gwen breaks into Hex's building and after fighting Charmcaster, she escaped by cutting the ground around her and falling through all the other floors into a torture room. There she finds an injured Ben. They fought Hex, Charmcaster, Kevin and her other minions and after Ben buys Gwen time and Gwen activates the time spell again. This time, she convinces both her other past selves not to interfere and wipes the memory of the Gwens that belong in that time period. The two time traveler Gwens go home and the present Gwen takes the present Ben, and present, mutated Kevin to Mr. Smoothie's. On the way, the gang runs into Paradox again who says everything is fine.
