Talking Slows Time

"Nope. It's just that Talking Slows Time."

Apparently, when people are talking before a moment that would either (severely) hurt or suddenly kill them, that's a cue for God to put time on slow-mo so then they can get their dialogues out of the way. This might or might not prevent the bad thing from happening.

Compare to Rewinding Cuts. They both disrupt the flow of spacetime in a way that's convenient to the characters being put in harm's way to some extent.
