As an addendum, in more literary works, the expectation will be addressed or otherwise dismissed--that's another more meta way to "reverse" it. In one of Pushkin's short stories, for example, he builds up this expectations regarding a duel (with guns) between two character. A lesser writer would play with the expectation regarding the outcome, i.e either A dies or B dies or they both die or none of them die etc. Instead Pushkin, knowing his reader has already read stories like that, does a time skip instead to many years after the duel, delaying the outcome to create further suspense and reversing the expectation of the expectation itself. Chekov does the same thing in his story, In The Cart, where he keeps bringing up the tall, dark, handsome bachelor, who the main character thinks is cute, only to completely dismiss him as a potential mate by the end, resulting in a far more profound "solution" to the story.
