We first saw Emily VanCamp when she starred on The WB's Everwood, but Emily already had a few credits to her acting resume before that, including a 2001 Canadian film called Lost and Delirious. The movie takes place at a girls' boarding school, where a new girl (Mischa Barton) discovers her two roommates are hooking up. Emily plays the younger sister of one of the roommates, and is horrified to discover them in bed together.
In this clip, Allison (Emily) confronts sister Tori (Jessica Paré) about what she saw. Seriously soapy stuff! Emily clearly had acting chops even as a young teen!
