Really, was this a set up?. He hadn't noticed. Angel swung into the fight more worried about parrying now then he had been, those blessed weapons hurt. What were they gonna get next, guys with crosses and holy water?
When two appeared Angel decided he just wasn't gonna think anymore. He instead thought about Spike and how this was all his fault somehow, he had a point about the targetted attacks, very targeted, they knew exactly what to hit them with and most vampires would be dead now. Not to mention, he didn't think backup was coming at all. If Spike really didn't know about the note he'd left Faith probab;y wouldn't either.
"Don't suppose you called Buffy on the way did you?" he asked, only half joking between the fighting.
" To be honest Spike, I was gonna asked who you'd pissed off enough but look at it, its got to be higher up only the Senior Partners could pull something this twisted off. More demons. More swords, dammit, clearly he'd pissed it off, whatever it was.
"Why's it fixating on us?" he mused going on the offensive and killing one of the demons that had been plauging him, the blessed swords he'd wrap up and bring back after this, nothing fancy but could be useful for the team to have a few of, he didn't know where they got their Holy Water or anything. For a while, he and Spike were distracted with fighting, Angel very much NOT thinking about anything at all, he didn't want to fight more stuff.
