Okay, it’ll be a little fuzzy, since it’s been a week or so, but…
Connor shows up and immediatly tries to kill Angel, and almost succeeds. He smacks the rest of the group around a bit, then runs off. Gunn and Fred head out to look for him overland, Angel goes through the sewers (it’s daytime) and Cordy and Groo stay beind to guard the still-open portal while Lorne looks up an old friend to seal it.
Connor finds a girl trying to get a fix from her dealer and his goons, who starts slapping her around. Connor intercedes, beats the crap out of the goons, and cuts off the dealer’s ear as a trophy. The girl leads Connor to an abandoned apartment where they start to get intimate. Before they do more than kiss, she excuses herself and goes into the bathroom to shoot up.
Meanwhile, Cordy and Groo are rendered unconscious by some sort of energy blast from the portal. They wake up when Lorne arrives with an odd blue-haired woman with a tendency to randomly teleport. She closes the portal, but warns that something else has come through. (Incidentally, the blue haired woman is uber-cool. I hope they bring her back some time.)
Fred and Gunn find the scene where Connor took down the dealer and his crew, and tell Angel about it, who tracks Connor down to the apartment. He gets there just as Connor finds the girl dead of an overdose in the bathroom. There’s a lot of emotional conflict, Connor tries to kill Angel again but without the element of surprise, isn’t a match for him. About this time, the dealer shows up again, with a vendetta for Connor. Angel and Connor gang up on the dealer, and Angel takes several bullets for Connor as they escape.
Connor, confused about Angel, parts with him on semi-amiable terms. Angel tells him he is always welcome at the hotel, and they go their seperate ways. Connor ends up in a bad part of town, and meets the elderly Holtz.
That’s as best as I remember it. I’m pretty sure Wes was in there somewhere, but I don’t remember what he did (probably more of Lilah trying to coerce him to change sides)
Sorry I can’t help you with West Wing.
