I am kind of like Angel in his attitude towards Xander as excerpted from "Enemies 3ABB17":
XANDER (cont'd)
Man, where've you been? You gotta
find Buffy - she's going to her place
and stocking up on...
CRACK! Without looking or breaking stride, Angel lashes out a mean right hand and cracks Xander across the jaw. Xander crumples to a heap, unconscious before he even hits the ground.
Angel and Faith just keep walking, out of frame.
ANGEL
(deadpan)
That guy just bugs me.
They keep going...
