2 logic mistakes?
1) Tyler tells Jack not to talk about him. But why isn't Jack surprised? He should not talk about Tyler with Marla for example. But Tyler f***s Marla. So she should know Tyler, could Jack think.
2) Bob asks Jack if he heard about Tyler. That Jack doesnt know about the other dates of Fight Club is clear (Tyler is there not Jack). But Bob should see that 'Cornelius' is Tyler. Or not?
