I still laugh every time I watch ‘School Hard’ and see that Spike seeing through Angel’s charade of being evil is presented as being such a twist of events, when later you see that Angelus is an actual dick to Spike 24/7, so of course Spike didn’t buy into the, “Hey, buddy! Ain’t it great that we’re evil?” thing Angel was doing, there. I mean, really.
Angel, pretending to be Angelus: Spike! Great to see ya, man! How about that Slayer? She’s scary, huh. I mean, you can try to take her but you’ll probably fail, so maybe just leave instead, buddy friend pal?
Actual Angelus: I think I’ll kill the Slayer’s friend’s fishes today. *Pushes Spike out of his wheelchair.* After I fuck your girlfriend, I mean.
