The First Vs Angel Investigations
I always wished the last arc of season 4 tied more directly into the final Buffy season, and had the Angel Investigations team help take on The First in the final run of episodes as opposed to the Jasmine storyline.
It got me thinking... who would The First appear to them as to really get under their skin and manipulate them?
Angel has countless victims from his Angelus days, and Gunn has an obvious answer with his sister. Who else could appear to them?
I'm especially interested in how Wes would deal with The First, as he's the most competent member of the team IMO. This would be fresh after the Angelus arc, so I suppose Lilah?
