Jessica is Sam's girlfriend at Stanford, where we first see Sam in the Pilot. In flashbacks of their life, she seems to make Sam really happy and not as pouty as he gets all on his own.
In the pilot, she is rudely introduced to Dean when he breaks in to come get Sam. First impressions are everything! But Jess seems to be quite easy-going about it. Sam leaves with Dean to look for their dad, and when he comes back, he finds Jess pinned to the ceiling, bleeding, and then bursting into flame -- exactly what happened to the boys' mother 22 years ago. She also was killed by the Yellow-Eyed Demon.
Jess and Sam apparently lived together for a while at school, and he never revealed much about himself or his family to her. She is buried in Palo Alto, California, and apparently thought that roses were lame. According to her gravestone, she was born on January 24, 1984, and died November 2, 2005.
Jessica puts in some real time on screen in Dean's hallucination in What Is and What Should Never Be. In the Djin-induced reverie, Dean enters a world in which Mary and Jessica both are alive, and Sam and Jess are still at Stanford and about to get married.
Jess next appeared in the season 5 episode Free to Be You and Me. But it turned out that it was Lucifer disguising himself to gain Sam's trust.
