What I’m thinking of is moments in fiction where, even though you’ve seen it before and know exactly what’s going to happen, you still hope - or fear - things will go another way.
For example, when I was a kid *The Jungle Book *was my favourite film, at the end the villain Shere Khan fights Baloo and I was always scared that Khan would kill him, even though I’d seen it dozens of times and knew he wouldn’t.
Or in The Great Escape, I always hope that on the bus that he won’t reply ‘thank you’ when the German wishes him good luck in English, even though I know he will.
Anyone know a more concise way to say what I’m on about? ‘Continued suspense’, maybe?
Tropes are something a writer uses, consciously or unconsciously, in constructing a story. You seem to be talking about a way that some audience members - certainly not all, and probably not most - might emotionally respond to certain story elements (and, let’s face it, it is mostly going to just be children). Fearing that it might go differently, or wanting it to, isn’t a trope, it is a response. (That said, I do not think the TVTropes is all that scrupulous about definitions, so they may possibly still have a page covering this sort of thing.)
