One great Pairing also known as Angelus and spike (when angel goes bad) they bicker with each other pretend they hate each other but secretly they like each other, and not in the sexual way as many S/A fans think ... Angel sired spike along with Drusilla (long story) anyways they are connected and kind of related in that way so em basically there 2 hot sexy vamps with souls.
see Spike and Angel too.
SPIKE: Oh, bollocks. I was just getting warmed up.
ANGEL: That was you hitting me?
SPIKE: The last bit, yeah. Hainsley's been dead since he hit the table. Oh, come on. Had to get a few licks in, didn't I?
