Jessica was picking flowers at the time of the battle. When she neared the town and saw it was destroyed, she ran away only to be found by the surviviers. Since she turned out to be the best thrower they had, she became a thrower. She is part of the original team.

In the first game, she sacrificed her body the entire time, again and again, to stall up opposing players. It eventually paid off as the team won the match and she earned an MVP!

In her second game, she threw the team's lone touchdown, and thus became a more accurate thrower as a result. This was the team's first learned skill.

She completed the game winning long pass to Steven in the third game, thus winning the match, after picking it up from a throw-in. After the game, she had to take Alex Forthmire under her wing and teach him how to play Blood Bowl. Although Alex doesn't like being taught by "some girlie" and thinks he is better than Jessica, she doesn't mind teaching him because she has a lot of patience and she belives that having the extra thrower around for when she cannot play is a great idea.
