"The Killer in Me" is the 13th episode of the seventh and final season of the television series Buffy the Vampire Slayer. Plot 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. Buffy goes to check on Spike, who is determined to remain chained in the basement until they know the First Evil is through with him. Suddenly, Spike begins to writhe in pain as his chip begins firing randomly without provocation. As Buffy and Spike talk about the potential causes of the chip's glitches, Buffy realizes that she will have to contact the people who implanted the chip in the first place: the Initiative. After failing to reach Riley Finn on the phone, Buffy and Spike go to the Initiative's abandoned base to look for the painkilling drugs that were used on Spike during his captivity there three years before, when the chip was implanted, and for documentation on the chip. Buffy and Spike wander through the remains of the Initiative, finding many dead soldiers and demons. Inside the Initiative's base, Buffy and Spike are attacked by a demon. During the fray, Buffy is wounded by the demon and when Spike tries to help, his chip fires and renders him ineffectual. As the demon grabs Spike and tries to drag him away, Buffy battles with and finally kills the demon. As she crouches down by Spike to see if he is okay, lights turn on, revealing a group of soldiers. Their leader explains that Riley received Buffy's message, and they are there to help Spike. An examination confirms that Spike's chip is killing him, and Buffy must decide whether to repair the chip or remove it. When Willow goes upstairs to bring Kennedy some tea, she finds that Kennedy is not actually sick, and is instead dressed for a "mission" which she says requires Willow's assistance, involving drinks at The Bronze where they get to know each other. After leaving the bar and returning home, Kennedy gives Willow an end-of-date kiss, with a surprising effect: Willow takes on the appearance of Warren Mears. Panicking, Willow rushes downstairs; on seeing her, the others recoil, partly because they know that the First has appeared to Andrew as Warren. Buffy hits "Warren", showing that "he" cannot be the First, who is incorporeal.
