Spider-Man: The New Animated Series

Head Over Heels (1x6)

:

Peter winds up getting partnered with the intelligent, but weird, Christina for a class experiment and it turns out she has a big interest in Spider-Man. She's also managed to create a mind reading device, but it short circuits and badly affects her mind. She now thinks Spider-Man is communicating with her and is bent on doing whatever it takes to be with him.
