Eventually, Fred discovers that it was actually her former professor's fault that she had been trapped in Pylea, and indeed, Professor Seidel had attempted to trap her in another world yet again. Furious, she plots to kill him with Wesley's help. Gunn feels that such a brutal act, even against Seidel, will ultimately destroy her. As a result, in a battle where she is trying to trap him in a hell dimension, Gunn snaps Seidel's neck himself and drops the body into the portal. Unfortunately, this causes a rift between Fred and Gunn, and ultimately ends their relationship.
