- Why didn't Logan tell Frances about his mission? The computer didn't forbid it and confiding with Frances would have helped. And anyway, Frances should have known Logan wasn't suddenly turning 30.
- The human mind can only process so much. Movie-Logan had just had 3 years of life stripped away and was given a 24-hours mission to complete. Explaining things to a man who doesn't *want* to know how things work (and actively needles Logan about asking questions), whose main join and purpose in life is killing people like his only informant (who hasn't given him much of a lead so far) would be exceedingly difficult in Logan and Francis' states of mind.
