>>212459470the last episode is "from tony's perspective". at multiple points there are strange cuts when he and the viewer "see" his literal immediate future, as well as one of the potential endings for him.
this happens when he goes and sees janice in her giant empty house, moving on after bobby's death and finally becoming her mother. then, again, when he goes to see junior rotting, confused and alone in a nursing home. even though he's "won" and "gotten away with it", he knows deep down he'll end up dead, in jail or alone.
in the final scene his paranoia is on full display and the cinematography highlights it - it focuses on the member's only jacket guy because tony is focused on him, not because he's acting particularly suspicious. tony's favourite scene from his favourite movie is when michael goes to the bathroom to retrieve a gun to kill some other gangsters. when member's only guy goes to the bathroom, that scene is playing in tony's head as his anxiety heightens and he expects death any second.
really, he may or may not die in that moment - it's deliberately ambiguous and david chase has gone to great pains to never confirm it either way - if he did die, you might think he'd have said at one point in the years since, wouldn't you? but even if tony survives, he already considers himself on borrowed time, a dead man walking - almost a fate worse than death in itself
