Trope has been launched. This was about binning it.
...given that it's overly short and has been untouched for 21 months.
Goo Monster, do you want to do anything to revive it? Like the new name you wanted two years ago? A better description would help, too, as well as marking up the examples with formatting and links.
So it's Twisted Echo Cut via Show Within a Show. I see what is unusual here, but whether it's worth depends on more examples.
The Regular Show and Legend of Korra examples need to be examined by someone who knows the shows in question, because they are so poorly written I'm not sure what the writer was actually trying to say.
It would also need a rename, of course. Like "Nested Twisted Echo" or something. A good point against it is that Twisted Echo Cut doesn't have much examples, so maybe it would be better to merge and note than separate.
Two months and no one has made any changes. If anyone wants to save this, you have until the end of the weekend.
It got 5 examples. Then again, it's not a lot, so this may as well be merged into Twisted Echo Cut.
