Jessica is the new girl at school, having moved to Beacon Hills from New York three weeks previously with her family. Jessica looks to make friends in school, but has trouble fitting in because of her dad being the new history teacher and is prone to unintentionally embarrassing her.
Jessica became pregnant with Aiden's baby after the two had unprotected sex at Scott's 18th birthday. Around the same time, her father was offered a new job teaching at a community college outside of Beacon Hills. Jessica told her father that she wanted to stay in Beacon Hills and attend college there. After her father moves away, Jessica attended Beacon Hills University. She returned to Beacon Hills heavily pregnant and reunited with Stiles until she went into labor with her child. Unable to find a doctor, Stiles preformed a caesarean section on Jessica due to her having placenta previa. She gave birth to daughter, Jenna.
