A Plot Twist
where another character in the story has accomplished one of your mission objectives for you. Unfortunately for you (or fortunately, depending on how you look at it), getting to the point to receive the MacGuffin
or benefit is just as hard as accomplishing the mission yourself. Alternatively, you may have to do an entire dungeon to get to one of your objectives, only to find out that someone else's done it.
Not to be confused with Bait-and-Switch Boss
, which is slightly similar and explicitly involves fighting a replacement boss.
