Answer:
Disillusion
Step-by-step explanation:
Juxtaposition is creating a contrast between two things, which doesn't really include subverting the reader's expectations. For a contrast to happen, two opposing objects of themes must exist within the story, and the expected scene does not.
Twists are used to change the direction of the plot. While the new setting may have plot significance, a twist would have to be more than that.
Worldbuilding could be an explination, but it isn't specific to a setting being unpredictable. This is the least likely, in my opinion.
That leaves disillusion, which makes the most sense to me. It's carefully dissapointing the reader without causing them to loose interest. An example of disillusion would be hosting the Golden Globes in a bar, unexpected and dissapointing compared to the expectations the audience holds, but interesting enough to make them wonder why.
