Andrew is cosplaying as Spike and being interrogated by Xander and Anya while Actual Spike is drinking blood out of bags and shattering chairs to bits (at the behest of another More Evil Spike). The scoobies would do well to remember that there are manacles in the basement, and everyone else would do well to remember that they could USE THE DOOR instead of BREAKING THE F*CKING WINDOWS AGAIN. It is Season 7 Episode 9: Never Leave Me!
