Buffy the Vampire Slayer 7x13

The Killer in Me

After sharing a lingering kiss with would-be Slayer Kennedy, Willow bafflingly transforms into Warren and must confront the loss of Tara. When Spike’s chip begins to malfunction, he and Buffy take a trip to the Initiative stomping grounds, where they meet up with a few remaining soldiers who give her a choice of how to deal with the problem. Meanwhile, when Giles takes the Potentials on a self discovery retreat, the rest of the gang are stunned when they discover clues that lead them to believe Giles may be The First Evil.
