In the prologue Josh and Chris are passed out drunk.

But later in Chapter 5, Chris and Ashley discover a toy house with dolls set up exactly how everyone was set up in the room during the prank. How would Josh have known where everyone was?

Also Chris says to Ashley "Great, so you're basically saying that we put a vulnerable friend in a terrible situation and essentially caused her to run away and never be heard from again?" But again, Chris was not actually part of the prank.

Which also makes the whole "torture Chris" part of the saw and gun challenge make NO SENSE. He gets tormented the most by Josh's planned revenge but he was also drunk and passed out.

Make it make sense?

I'm surprised they didn't fix this in the remake by simply having Chris part of the prank.
