Plothole

"9. They require that the personages of a tale shall confine themselves to possibilities and let miracles alone; or, if they venture a miracle, the author must so plausibly set it forth as to make it look possible and reasonable" -- Mark Twain, "Fenimore Cooper's Literary Offenses"

A plothole is created whenever something in the story doesn't make sense. This can either be through bad characterization, inconsistent plotting, or the existence of something contradicted in canon. They are often found in badfic.

Plotholes occasionally appear in HQ, and can be used to travel.

They are related to Logic Loopholes.
