Yaaaaa! [Subaru, instead of being thrown against the wall, is the lucky one that is simply blown further down the corridor and has a softer landing as he ends up face down on sand.

Moving sand. When he pushes himself up, the sand slips out from under him and pulls him downwards, and every attempt to crawl out only makes the sand give away faster.

He's fallen in the sinkhole.]

A-aaaah!
