Dark Reflection by Daniel_Nieves Rated: AO-AdultsOnly
Summary: Things can't get any worse for Spike. But when Warren shows up in Buffy's backyard with a gun, Spike realizes he was wrong. In an attempt to kill the Slayer, he shoots Dawn, putting her in a coma from which she won't wake up from. This action sets the Slayer off in a dark path, one that leads to self-destruction, as well as anyone standing in the way of her vengeance.
