In Manny's defense they probably shouldn't have been standing so close to the door.

I did think about some different panel angles to make it clearer what's going on here, but if you go too far down that route you end up with overhead panels and motion arrows. In the end I thought this panel layout worked (and, as ever, the copy-and-paste action ended up more work than otherwise), so I decided that I would go with it and if nobody got it I would just say it was subtle.
