It looks like Brendon threatened production 6/7 times and saying he doesn't want to be there. Even so J/J should have picked them because Brenchel are two big babies. All it takes is a lollipop for them to suckle on and they're good.

Brendon threatening production makes no sense because there is an emergency exit. All houseguests past and present know about the emergency exit. If Brendon really wants to leave he knows where to go.
