"We're sorry, but the number you have dialed has been disconnected or out of service since before this comic even started, thereby making this call a terrifying twist ending. Please hang up now."It's the oldest trick in the book, really. The plot leads toward an inevitable conclusion, then, at the last possible minute, we throw something in that changes everything. It looks like the cops have an open and shut case against the Scary Minority Suspect, but then, BAM, a crucial piece of evidence turns up to set them straight. It looks like our heroes are totally boned, then BAM, the Forgotten Superweapon or The Cavalry turns up. It looks like our Dom Com family has finally hit it big and won the lottery then BAM, the ticket gets eaten.

The other problem with the Twist Ending is that it walks a mighty fine line: if it's too in-keeping with the direction of the story, it doesn't qualify as a twist. If it's too far out-of-keeping, it comes off as a Deus or Diabolus ex Machina and the viewer feels cheated. The Twist Ending is the usual way of implementing a Reset Button, a Your Princess Is in Another Castle moment, or ensuring that Failure Is the Only Option.

Not to be confused with Tragedy. Subtrope of Plot Twist. Also see Movie Twist List, It Was His Sled. Contrast The Untwist, Meta Twist and The Ending Changes Everything.
