The Troika s latest scheme, a new device which will make women their mindless slaves, goes horribly wrong when Warren s ex-girlfriend Katrina is accidentally killed. The trio use magic to make Buffy think that she has killed Katrina - and it works. Between finding out the truth about her resurrection and believing that she has killed an innocent girl, Buffy s world begins to fall apart, and she ends up revealing to Tara that she and Spike have had sex.
