My favourite eps:
St. Elmo's Fire (who died): We get our second episode in a row with multiple deaths. First we lose Reverend Fain in the woods, then Kelly Seaver appears to hang herself, and then Harper's Island's Paris Hilton knock-off, socialite Lucy Daramour, is offed. It was the pits.
Baby Got Back (who died)
Barely-a-character Beth and Cheating Katherine Wellington.
Hollaback Girl (how they died)
It's unclear exactly what happened to Beth, but she is very creepily left in a tunnel underneath the hotel. Katherine is stabbed in the back with a pair of pruning shears.
What's your fave? ^
