He steps closer to the left corner, the offending location.
The big dent is still there from where he pitched the left half of door.

For his feet are turning cold in the draft coming in from the tiny, tiny crack in the supposedly solid wall.
“A hidden passage... I take it this won’t end well for me then,” he murmurs, recalling how he died in a sandy cave a couple of weeks ago.
He looks down quickly at his boots before pushing against the crack.
Ice is forming on the rounds of his boot-toes.
He pulls open the strange sliding door now revealed by the sliver of creeping cold air, and steps inside to find...
“It’s you? But you’re... not this way. Not... this! Agh!”
A pale hand crawls out from the opening, and shuts the door again, sealing the secret of Kenny’s disappearance away with a tidy little laugh.
