"Well, don't be. It's already happened thrice."
A response to “I’m sorry for your loss. Your mother was a great woman.” She was never human, and neither is her child.

"It already happened."
The hero didn't arrive in time to stop the antagonist.
"What, did you think I didn't KNOW that?"
A time travel story where the twist is that the story is a time travel story, the villain says the above line to the hero regarding how their efforts are for naught as their plans bore fruit before the hero even went to school as the two are battling each other inside a Dyson sphere.

“You look to the rising sun as a sign from your gods that they will aid you. I would temper that hope, if I were you. You’d be quite disappointed to find the sun’s warmth dare not grace us here in the darkest of places.”
A mythical being with multiple alleged sightings has been discovered by the protagonists...along with the person that built the thing.
So, you had found it huh?
