Keep forgetting he's in this episode to be honest To me they just had him there as a token because its the last one before the big finale. Not sure his part works too well IMO. Think IOHEFY would have been a much better choice to go before Becoming.I just remember that the guy who played Michael Scofield in Prison Break is in this episode.
I liked Angelus' brief role in this episode and him spitting out the blood gave Buffy the clue that something was up with the swim team.
This is one of my least favourite season 2 episodes. It's sandwiched between IOHEFY and Becoming which I think doesn't do it any favours. It's pretty much a standalone episode which would've been better off pre-Angelus arc.
