JESSICA STROUP on her role on 20210

The 23-year-old actress plays the bipolar Silver on the reincarnation of "90210" on the CW network. The show's second season makes its premiere Tuesday night. Stroup says she's careful not to play Silver's mood swings too over the top. She says she did as much research on the disorder as she could because "it's something that touches so many people but isn't really explored." Stroup says some people "have reached out to me to say they watched and it meant a lot." Like the original show from the 1990s, "90210" follows a group of teenagers in Beverly Hills. "90210" will air at 8 p.m. EDT on the CW. ___ On the Net: "90210": http://www.cwtv.com/shows/90210 sweetpea-honeybun
