Angel. It should be Angel, for it not to be would be a complete let down after they've been building it up that way for all these Seasons. And I don't want both to get it, Spike has a soul and thats good enough.
Whistler: It wasn't supposed to go down like this. (moves away from the wall) Nobody saw you coming. I figured this for Angel's big day. But I thought he was here to *stop* Acathla, not to bring him forth. Then you two made with the smoochies... now he's a creep again. Now, what are you gonna do? W-what are you prepared to do?
Seems like this was an opportunity for Angel to become human.
Obviously later on in Ats s1, from I Will Remember You, then with the last two eps for that season.
Angel: "It was the demon's blood. It wasn't the Powers-That-Be that did this?"
Man: "The Powers-That-Be? Did you save humanity? Avert the Apocalypse?"
Woman: "You faced a Mohra demon. Life goes on."
Blind Date
Wesley takes the metal tube out of the open briefcase.
Wesley: "Angel, what's this?"
Angel: "I'm not sure."
Wesley pulls a roll of parchment out of the tube and unrolls it part way.
Wesley: "Ancient Aramaic, if I'm not mistaken."
Cordy puts a disk into the zip drive.
Angel: "Yeah?"
Wesley: "Was there a reason you took this?"
Angel: "Yeah."
Wesley: "And that would be..."
Angel: "I - I don't really know."
I dont see them going back on all of this when it's been built up so much over the years.
