Having bad literary ideas.
Like: Character has been abducted by someone who knows his methods.
The location they are hidden at is at the bottom of a deep icy lake on an ice planet.
Best way of keeping a nutty character who is not normally afraid of breaching the hull of stations from doing just that.
We have a deep icy pond across our side yard. (It’s actually the neighbor’s deep icy pond. It has some nasty turtle-types which may have been responsible for the demise of a couple of ducks.)
