"90210" � (9:00-10:00 p.m. ET)

"Off The Rails" (TV-14) (HDTV)

JENNIE GARTH AND ANN GILLESPIE GUEST STAR IN THE EPISODE DIRECTED BY JASON PRIESTLEY � On a very special 90210, Ryan (Ryan Eggold) attempts to calm Silver (Jessica Stroup) down after reactions to her video, but she disappears before he can help. Dixon (Tristan Wilds) reveals the situation to Debbie (Lori Loughlin) and Harry (Rob Estes), who are shocked at the details and confront him about not seeking their help sooner about Silver's behavior. Kelly (Jennie Garth) and Ryan search the streets and show up at Jackie's (guest star Ann Gillespie, "Beverly Hills, 90210") home looking for Silver, but the visit proves pointless when harsh words are exchanged. Adrianna (Jessica Lowndes) is unsure how to care for a child but when she and Navid (Michael Steger) offer to babysit for Kelly, but the two prove to be better at the situation than they thought. Kelly and her friends fear the worst and search for her, not knowing where she is or what is causing her emotional behavior. Shenae Grimes, Dustin Milligan and AnnaLynne McCord also star. Jason Priestley directed the episode written by Steve Hanna (#118).
