I started watching 90210 during the first season but then due to moving I havent watched season 2 or 3 and ive started watching season 4 but have no clue whats going on "/ Can somebody please help me by telling me whats been happening?

I'll try my best. So you know Naomi was dating Liam in season so I guess you're like what's going on with him & Annie if you never got there. Okay, Naomi & Liam did date season 1 & Jen screwed it up, but they reunited. Naomi became a bit caught up with worrying about how 2 deal with Jen trying to ruin her life when she returned season 2 and wasn't exactly there for liam the way he needed her to be which resulted in him getting closer to Annie who was there 4 him when Naomi wasn't. Liam dumped Naomi, then fell in love with Annie. Annie wouldn't go out with him because of Naomi, but Naomi gave them her blessing. Ade got famous & became self obsessed which resulted in Silver thinking she had a right to steal Navid because of it which Ade was not happy about, so she sent a naked pic around the school of Silver, then Silver did things 2 Ade, then Ade took a little far by swapping out Silver's bipolar pills causing Silver 2 nearly go crazy & almost commit suicide which Ade didn't know it would go that far. Ade became an outcast from the rest of the crew because of it. Dixon was the only 1 that didn't judge her for it like everyone else. He became a drug addict & Ade helped him through it resulting in them developing feelings for each other. Now they are 1 of the cutest couples on the show. Ivy married Raj who is dieing from cancer, but realizing how much she'll suffer when he dies, he recently lied & told her the cancer disappeared so she'd think he wasn't dieing and live a happy life. Now she's dating some other guy in the meantime since Raj dumped her. Hope that brought you far enough up to speed:) Sub my youtube channel BrendaMckay2 to stay posted.
