A Fire Exit which leads to the camera-runs which lead you directly outside the compound and to safety in the event of a fire/emergency. John was stopped initially by either a cameraman or security, then by Dave/JJ, then spoken to by production staff who told him if he passes thru 1 more door, the party's over as he will be outside.

It is the same kind of dealio that Siavash/Marcus/Sophie did last year.

Interestingly enough, Lisa went further as she was led outside and shown sat in a portacabin for an hour before being talked into returning.

Not sure what kind of magical FIRE EXITS you're imagining as the house is essentially surrounded by camera-runs on all sides.
