Season 4 Complete!

[s4r4h3r0wn]

I've just finished season 4 of BH 90210. I read on Wikipedia that Shannen Doherty isn't in the show anymore, but I read the synopsis for the first episode of season 5 and it talks about her. Is she actually in the show or do they just make references to her? I think I'm going to miss her on the show.

I can't decide if I want to start watching season 5 tonight or not.. it might be a bad idea because I have to get up in the morning, and I know if I start I won't want to stop myself!
