Plot hole: After learning about the prophecy, the gang realise that Spike's headed off already, getting a head start. Angel grabs another car and heads after him, but why use a car? We find out in the first or second episode this series that he's got access to a helicopter, which he uses to get a long way ahead of some bad guys, and which would have saved a lot of hassle this time. Can't imagine Wolfram and Hart's pilots only work in the daytime.

Visible crew/equipment: When Angel is fighting the demon, you can see an obvious camera and two hands in the bottom right corner. (00:27:10)
Cordelia: You want I should distract him? Make with the nice-nice while you slip by?
Angel: Don't be stupid. I'm that guy and the most beautiful woman I've ever seen is making eyes at me? It's either a bachelor party or a scam.
Cordelia: What did you just call me?
Angel: I'm sorry. You're not stupid.
Cordelia: No, after that.
Trivia: In the opening credits there is a shot of a girl standing alone on the corner of a street. This was taken from the Buffy episode "Anne", when Buffy was staying in Los Angeles.

Answer: Due to his epiphany, Angel basically had the 'true darkness' he worked so hard to reattain ripped away from him, like his soul was after sleeping with Buffy.
