What is this trope called in movies?

One example is in Oppenheimer: Strauss asks who is the young senator and the guy replied it's Kennedy.

Other example in The Dark Knight Rises :

You should use your real name more often. I like it. Robin.

The trope where the in movie characters don't know but for us audience it's like Holy Shit! Moment.

I would like to know which other movies have this kind of foreshadowing (?) .
