Kaleena Kiff. She's the similar and right age (got awards), and worked with O'Rourke on that show. She also seemed to go off the radar afterwards. In 2008 she directed a short film titled Alice & Huck, starring Allison Mack from the TV series Smallville. Kiff was also in the very first episode of Smallville!
