If anyone remembers Jessica was the first person to say something in the Pilot episode. It was not Sam or Dean! Wow.
Anyways! Adrianne seemed like just the right person to play Jessica; Sams girlfriend. She had the looks, the charisma and the height! Sam is tall enough as it is. I think she is a great actress, and I especially love seeing her in the season 2 episode 'What is and What Should Never Be'. She plays a real charming person who deserves a great guy like Sam. Overall I was very impressed with her actiong skills and I hope she pops up again for a little bit in season 3.
