Jackie Geary (born September 7, 1975) was the girlfriend of Adam Goldberg. She is portrayed by Alexis G. Zall and was introduced in the fourth season of the show.
Jackie and Adam shared a kiss in the fourth season finale, The Day After the Day After. She was very similar to Adam in many ways; for example, they like a lot of the same nerdy fandoms. But, while Jackie liked Star Trek, Adam was forever a fan of Star Wars, and Force Freaks and Trekkies do NOT get along.
Jackie and Adam broke up because Jackie had to go to college. Jackie was in New York for the summer and returned in You Got Zuko'd. Adam was scared that Jackie would break up with him because she seemed to like new things and wasn't as nerdy as she had been before. Jackie's last regular appearance was in the season 6 finale, Breakin', though she was mentioned in Dana's Back. She appeared once more in season 10's Push It.
Jackie was portrayed by Rowan Blanchard in seasons 4-5, and was then portrayed by Alexis G. Zall in seasons 6 and 10.
