If Heller said that they would not be fooling the audience from here on out and that there is NO TWISTS then is he telling the truth ( it's possible he is and it is in fact Bertram) AND if he isn't telling the truth and lying yet again then what makes us think that the list is genuine. If he lied about one thing then he most likely is lying about something else. 

TRUST NOTHING. lol. He has us.
