I need to know if this would be confusing for a reader if such a thing happened in the plot. I have three MC characters. Two of them are being held prisoner together, one is elsewhere doing their own thing, unknown currently to the other two characters. The story is a little bit sci-fi mixed with zombie horror. I've currently left one of the captured MC's in an unconscious state, brought on by the captors. Here's the question: If I totally change the character's setting into an apartment with the other MC, totally alternating her reality, and recent past...this will later be revealed to be a false reality, would it confuse the reader as to what is going on too much and pull them from the story? Would it break the suspension of belief?
