Once Rob Thomas actually gives Shelly a line, we'll give her a quote.
Veronica was drugged and raped at an 09er party at Shelly's house. Her dad served as ambassador to Belgium. I know, not exactly the most interesting bio, but what do you expect from a character who has yet to utter a single word?
We don't know the name of the actress who plays Shelly Pomroy. She might have appeared in 1.01 "Pilot," 1.02 "Credit Where Credit's Due," 1.03 "Meet John Smith," 1.06 "Return of the Kane," 1.10 "An Echolls Family Christmas," and 1.15 "Ruskie Business," but it's kinda hard to tell because she's just a background extra.
Shelly Pomroy (aka Shelly 2.0)
Forget about Veronica, the real victim of Shelly's party was Shelly Pomroy. Poor thing was so traumatized by the events of that night that she changed her hair color, hair style, build, and face in the second set of flashbacks.
Melissa Hoover plays Shelly Pomroy 2.0.
Shelly Pomroy (aka Shelly 3.0?)
You can't have a Veronica Mars season without having a Shelly controversy, and once again Rob has managed to confound us with yet another Shelly question.
Because of a crooked drug test, Shelly Pomroy took over Meg's spot as head cheerleader. Is this head-cheerleader Shelly the blonde, wordless Shelly 1.0 from the beginning of season 1? Or is she the brunette, moaning Shelly 2.0 from 1.21 "A Trip to the Dentist"?
We dunno. All we know for sure is that we are the ONLY site insane enough to devote three bios to a character who has yet to utter a single word.
All bios: 2.20 2.01 1.21 1.01
