World Enough and Time

I like the sense that Buffy is attracted to Faith and her lifestyle - tempted - but when she gets too close, doesn't like it.

Yeah. This becomes more overt later - as I'm sure you know by now, judging by some comments above.

Cordelia really comes out very well in this episode.

She does have her moments. On a meta level, I think they're building her up to increase the guilt factor of Willow/Xander.
