Though this will be smaller than the previous spoilers, I'll be touching on the characters who will be appearing in L.A. during the second half of the Prologue Season. This'll be smaller mainly because these characters haven't actually appeared in any episodes yet. If you were hoping for Buffy spoilers (hopefully that'll catch your eye) go to The Spoiler Slayer. That's all. Oh well, enjoy: Dimitri: Dimitri will be the third member of the party. Dimitri will be joining with Jay and Isis during Season One (they'll be half of the main cast), the Dimitri in Season One will be slightly different from the one you meet in L.A. Dimitri is a type of seer demon (he's only half-demon though), who can look into peoples thoughts (similar to Buffy in Earshot), and he'll have connections with Wolfram & Hart. Eventually, he becomes fully human- except for his seer abilities (which manages to keep). Though is abilities aren't harming his brain like Cordelia's in Season Three, they might him slightly crazy- and it's always a possibility that he'll eventually go crazy in the future. He goes to Hawthorne with Jay and Isis in Season One. Keeley: Originally suppose to be related to Kate (which I thought would be lame after awhile) Keeley is a girl who was suppose to be in Jerrold's class in L.A.- though after some weird stuff happens in L.A., her parents move to San Francisco, and she ends up going to Hawthorne High School. Keeley is very religious, but is still kinda loose about the whole thing (she has a stake-cross, similar to Kate which was why I originally had plans for them to be related). She likes Jay at first, especially when he saves her, but then when she discovers she's a half-vampire she freaks out. In SF, she avoids Jay and later does a spell (concerning holy water and cross) to harm him. Salma: Salma, who is briefly a kid in Jay's class in L.A., is turned into a vampire by Damien. Isis chooses not to kill Salma and she flees. Selma later reappears in the first episode of Season One, and she joins up with a group of vampires and she'll be a reoccurring character throughout Season One. Leo: He's a lawyer. While in L.A., Jay attracts Wolfram & Hart's attention (first as a tool to torment Angel, then later they want him for other reasons). Leo, who was in charge of capturing Jay, is forced to follow Jay to San Francisco in order to go after Jay. Later, Leo begins to develop of a personal reason in the hunt for Jay. Leo, however, is not teaming up with Lohesh and Damien, and they do not become allies. Giovanni and Celeste - Giovanni and Celeste are two one-shot characters in the Prologue Season, however they do play vital roles. Giovanni is a part of Jay's past (briefly in Angel's, though it's less important) and will play reoccuring roles about his past. So Giovanni has some importance. Celeste (who will appear in a funny episode with Cordelia) is related to Isis's past. Celeste will also be a star/reoccuring role (villain) in the "Alliance" series, and will later reappear in Season Two. It's doubtful she'll return for Season One though.
That's all, pretty much. If you think I spoiled too much, you'll still end up being surprised, trust me (this is only a very little portion of the stuff that'll happen). And more characters are on their way. Hope you enjoyed, and if you want to see the previous spoiler, just look below:
