Plot Saver

Think of life savers but they're for the plot.

A Plot Saver is an UnTrash that keeps the plot from going down a path that the creators find undesirable. Plot Savers that are planted in the plot come in many forms: All Just A Dream (and other similar UnTrashes), Plot Said To Do It, and Ex Machina. They're played just before some horrible (commonly fatal) thing happens to the main characters as the story must shape itself in any way to keep them alive for future events.
