I'm writing an action scene and I'd like for the POV and the readers to realize something at around the same time. Specifically, why another character is physically stuck and unable to escape an advancing danger.
If the readers figure out that it's the POV's fault before the POV does, they might wonder why the POV is so stupid, or blind, or whatever, even though I'm going to great lengths to show the character as being clever. If, on the other hand, the POV realizes something that the readers couldn't've foreseen, it will look like the author hasn't done his job setting the scene and placing hints.
So, ideally, the reader and the POV would figure it out at the same time. The problem is that I as the author know the surprise, so I can't pretend to figure it out. I know there are authors out there who are really good at surprising the reader with things the reader should've already figured out. Are there strategies for achieving this?
