Episode 3 predictions

I think that the guy living in his car will be the one to press the button. I also think he's smart enough to have realized that the strategy is to closely watch and wait until someone flinches for the button.

I'd eat my shoe is the Jesus guy is the one who button presses. The African lady and the other person I can't read too well.

Also I think it's getting narrowed down to 100 next episode.
