[@Vertigo] Yep, the picture definitely looks like the characters are meant to fish something out of the drain in the room. Dunno where they'd get a hook and string, but one option is the wire Pebble pulled from the cabinet. Depending on how hard the metal parts are and how long the wire is, it might work, but then again if the drain's wet then it might ruin the wire.

Doorwise, yeah, Duncan's set to just try and open it. His foot fit, so his hand probably will (unless he's that misproportioned lol). I will say, though, that if something grabs him when he reaches his hand out, I'm gonna have an internal heart attack through the screen.

Airvent-wise, totally didn't think about that! Honestly the whole drain + airvent combo said 'serial killer's murder dungeon toned down' to me since, ya know, sleeping gas + drain for clean-up. Glad the door worked too haha
