Theory: Jeff knew Twana would be on the elimination vote card.

Jeff tried deceiving her by saying she was the least likely to be on it even though it would seem she’d be a top target among the 50 participant anonymous vote. Not because she deserved it, but she was widely regarded as a leader and Jeff’s intelligence and gamesmanship understood that she’d be more likely than anyone simply because of her notoriety. I believe he tried to deceive his strongest competition, but it was rendered irrelevant by the 1M self-elimination.
