well I still am hoping its Bradon, but that curly mop head on the kid does indicate Steve, but I would be so sad that he and Janet would break up, and also I don't think Steve is the kind of person to leave his kid.
As for Brandon leaving the kid, she said he was involved at first but then left, I can see Brandon getting a job offer and Kelly telling him he should take it and then him being gone and it just being hard to get back involved in the child's life...just seems like Brandon.
I do think they are trying to put Erin (I can't call her Silver, her name is Erin) and Dixon together but they make a strange couple, he is a little too geeky for her, but we'll see, he seems to like her and they obviously have something in common.
I guess we will just have to see what happens.
oh and as far as old cast members coming back, here's my theory, if the show stays popular and does well, the old cast will come back because none of them really have anything else going on for them, so they have nothing to lose, they are typecast anyway. Most of them have had a hard time finding success otherwise because people only think of them as their 90210 characters, I think that's why Jennie Garth came back, its either that or reality TV.
