Who didn't love Oz? I mean yay for lesbian Willow and all, and I thought she and Tara were adorable (probably the first lesbian couple I was ever exposed to thank you Joss) But I always wanted Oz to come back. It think it's just Seth Green I just want to pinch him and love him for ever and ever...

isnt anybody else curious to see what good ole oz has been up to since season 4? i am!

I really wanted Oz to come back and be with Willow.(Don't get me wrong I really like Tara but I just loved Oz and Willow as a couple)

Tara most of all but of those listed Darla. Especially in that school girl outfit.

I LOVED Oz! :D
Angel(us) Wesley and Cordelia I loved how they moved on with their lives in LA and became different people, so them coming back to SD would've been different. they wouldn't had fit...as for everyone else, they left just at the right time. and when they did appear on a ep or two, it was worth the watch. :)

Cordy!

Wes, Cordy, Angel/Angelus got the spinoff, which worked for me. We still had the characters. (although I would have loved more crossovers. I'm just a sucker that way.)

Darla & Dru were on Angel, so we still knew what was going on with them.

Riley, Parker and Kathy? Who really cared about them anyway?

So that leaves one. Oz. I always really wanted to know what happened to him. Would have LOVED if he came back as a guest star on Buffy OR Angel.

I really have loved to see Tara come back, but out of the choices above i would have to say Cordy, she had quite a few different sides to her.

All of them would have been great except for Riley, Parker and Kathy

I would have picked angel but he came back...
