He wants you to walk away and not make a scene. Do the opposite. But be calm and non-threatening, give him an out. Make it clear that you are not accusing him of anything, so he can walk away from his botched job.

What T stop was this, by the way? I can't imagine any place would be empty during the morning commute.

it takes some stones, but i like this line. i'd be pretty shocked if they tried to kick the crap out of you in a crowded T. it'd also be a little nerve-wracking leaving if they exited the train at the same time (can't imagine they would), but you could call the cops for an escort if you needed to.
