"Curse your sudden but inevitable betrayal!"
How characters betray each other's trust. Usually a Plot Twist of some kind, except when it isn't.
Contrast A Trusting Index and Loyalty Tropes. See also Disguise Tropes, Face Heel Index, and Friendly Fire Index.
Of course, beware of spoilers in these tropes.
