SPOILERS....BEWARE

Bros/Hos:
04/13 - Out of patience waiting for Tommy to return home, Julia makes a life-changing decision about the future, Robert discovers what Kitty has been keeping from him, and Holly and Sarah finally find balance in their relationship.
90210:
04/13 - Ethan's not the only one saying goodbye to the high school. Silver actually makes her exit in Tuesday night's episode as well. Because of her breakdown, little Silver can't show her face at school without being scrutinized, so she's heading off to an all girls Catholic school. Jessica teases, "As far as the recovery goes though, she's trying things out. When we come back, she's already on her medication. She's going through a routine instead of just being out with her friends and letting too much influence her, and let her emotions get to her too much and go into another episode. As far as the rest of the season, it's figuring out what works for her and getting back to Silver because she loses touch with that again." [...] Donna Martin returning to 90210 is by far the best thing that could've happened. Putting Kelly (Jennie Garth) and Donna back together is comedic gold, especially when the pair accidentally end up in a gay bar.
