severance season two finale understands tragedy better than most stories overall, actually. a good tragedy doesn't need a villain. mark s. is not the villain. mark scout is not the villain. they're both selfish and impulsive and deeply human. gemma and mark scout can't be happy without dooming mark s and helly r, and vice versa. that's good tragedy right there. there was no right decision to make. it was always going to be this way. two hearts, one body; you can't follow both. they want the same thing: a happy ending with the woman they love. but a happy ending for one is always going to a tragedy for the other.
mark s's loyalty to his outie was what drove him to this point, but when he sees gemma, i think he realizes that he doesn't owe mark scout anything. because what has mark scout ever given him? why should he, a full human being of his own right, willingly walk into his death for a man he's only spoken to once? it's selfish. of course it is. but everything mark scout has done up until this point has been nothing except equally as selfish. it's unfair to expect mark s to sacrifice everything there is to himself just so mark scout and gemma can be together again. it's also unfair to expect mark scout to let mark s take his body and life to pursue his own.
that's the thing about tragedy. there is no fair option. someone's always going to suffer. this time, it was mark scout and gemma.
