Thrown Down a Well

Throw the Jew down the well, so my country can be free...

—Borat, Da Ali G Show

A character gets rid of another character by physically or magically trapping them within some uncomfortable location, so remote it will be impossible for them to escape by themselves.

This is a way to do the death/resurrection plot without cheapening death, since the trapped character is always brought back.

A fun word for a prison of this type is "oubliette" where a prisoner would be thrown to be literally forgotten about (from "oublier" = "to forget").

Related to Out of Sight, Out of Mind and Put on a Bus. Compare And I Must Scream.

In DiC's Sailor Moon dub the Doom and Gloom girls trap each of the Sailor Scouts in the Negaverse except for Sailor Moon in the first season finale, Sailor Moon's magic frees them all and wipes their memories in the next episode.

Wolverine decides this is the best time to get rid of the competition for Jean Grey and chucks him down. Luckily for Cyke but not really for Wolvie, he survives, undoes his disjointing, climbs out of the fucking pit, and reaches the X-Men a few weeks later. Wolverine goes "I was a twat. Do what you have to." - what Cyke "had to do" was ZORT him in a single blast, leaving him naked, scorched and knocked the FUCK out in an Alaskan terrain. The rest of the X-Men witnessed this, and he called them to action to fight the bad guy. And followed him, ignoring whatever the fuck happened to Wolverine.
