Ok. Alice can predict Bob's move given Alice's move.

Ok, but if Alice can decide what to predict Bob's move will be given her own move, that means Alice can control Bob's move.

To some extent yes. But it depends on what function Bob implements. If Bob always playes Defect, Alice has no way of making him playing Cooperate (likewise, if he always playes Cooperate, Alice can't make him play Defect).

Yes, but didn't we already establish that Bob would always defect, because he had nothing to gain in either case, in which case he will defect no matter what Alice chooses? Or is Bob also a TDT-style agent?

Bob is 'rational'. Interpret this according to the decision theory of your choice.
