Thou Echo, thou art mortal, all men know.
A character asks a question out loud. A voice answers — but not in its own words, just repeating the last few words of the character’s question. The voice in question may just be an echo of the character’s voice; in which case they may or may not mistake it for another character. If the answering voice is in fact a separate entity, expect the character asking the question to assume the answering voice is their own echo, whether or not it sounds like them.
- My Little Pony: The Movie had a song done entirely like this between Baby Lickety Split, who was bemoaning her troubles at a well, and Flutter Pony Morning Glory, who was trapped inside.

No one has the luck I do (I do)
No one's had the set backs I have (I have)
Look where life has led me to (Me too!)

The bridge, as I say, was arched and covered in, in a very ridiculous manner, and there was a most uncomfortable echo about it at all times—an echo which I never before so particularly observed as when I uttered the four last words of my remark.
