"The Killer in Me" is the 13th episode of the seventh and final season of the television series Buffy the Vampire Slayer.
[1][2] Giles prepares to take all of the Potentials – except Kennedy, who is sick with the flu – on a trip to the desert to meet the First Slayer.
As Willow and Kennedy attempt to break the spell, Robson, a Watcher, calls Buffy's house from England and reports that Giles may have been killed by a Bringer who had attacked him in London several weeks before.
The Scoobies become alarmed when none of them can remember seeing Giles touch or carry anything since his return; no one has hugged him, and he is not driving the car to the desert.
Xander, Anya, Dawn, and Andrew all go to the desert to find Giles and, in the case of danger, stop him from hurting the Potentials.
After the meeting, Kennedy returns to the lecture hall to find Amy packing up as the rest of the group has left.
Willow, increasingly dominated by the Warren persona, goes to buy a gun of the same model that killed Tara and wounded Buffy.
Willow tearfully explains that when Kennedy kissed her she let go of Tara's memory for a moment, making her truly dead.
"[3] Anthony Stewart Head was not allowed to touch anything while onscreen for several episodes prior to this one, in order to set up the suspicion that Giles might actually be the First.
"[4] In the DVD commentary, director David Solomon notes that Iyari Limon had to do a lot of kissing in this episode.
Vox, ranking it at #110 of all 144 episodes on their "Worst to Best" list, writes, "Many of season seven’s most significant missteps involve one of two things: trying to find atonement for Willow in the wake of her dark choices at the end of season six, and her new girlfriend, Kennedy, who’s not a terribly interesting character.
