Willow:  It 's a text message . Oh , it 's from Xander . It 's one of our signals .
Amanda: Signals ?
Willow: Yeah , the system we set up a while back . Like codes . Uh , this _ one _ 's either " I just got lucky , do n't call me for a while " or " my date 's a demon who 's trying to kill me . "
Kennedy: You do n't remember which ?
Willow: It was a long time ago .
Dawn: Well , if we play the percentages ...
Giles: Something 's eating Xander 's head .
Anya: Say , that 's gratifying .
