A whole lot of nothing. The area that he is supposedly investigating (really

) is titled as "old hospice" and yet the 10 secs before he is opening the door to the storageroom has a shot of a hospital bed, which while unmade, is not old nor worn nor dirty. The storageroom has everything that seems to be some personal items of people neatly folded on the shelves, with the exception of the one item that happens to be on the floor as he opens the door. Yep really scary stuff. The "thing" that can only be seen in slow mo - again if we can only see it in slow mo, how does he even see things that we don't, unless in slow mo? - maybe just the shadow of the door opening.
He wants viewers, nothing else.
