Obviously we know what is going to happen because it's not live but I would really like it if your main guy decided the only was out was to kill them both and then himself. That would really make Derren look silly.
I remember Derren's very first tv show. It was some guy volunteered to play Russian Roulette live on tv. 1 time out of 6 that guy would've blown his brains out and made Derren look like a fool loollooloolol
Was that not the one where it was Derren who had the gun to his head, but the guy told him whether or not to pull the trigger? Because I'm pretty sure he fessed up that it was fake.
