So why did the Knight abduct Undyne anyway? Seems like a really bad idea to make the chief of police disappear. People are gonna notice she's missing.

Also, she's got shonen strength, inexplicable superpowers, and a desperate need to have something to actually do. Kinda inviting trouble with this.

Poor Undyne.
