i fully respect the decision mark s. made because i would have made the exact same one if i was in his position. if both of my options are getting me killed, i’m choosing the one where i die with the person i love, and maybe get an extra hour or two of life. why would i walk out of that door and die without taking any possible chance to fight? why would anyone expect another human being to just do that? why should mark s. just do what his outie says, when it’s going to cost him and the people he loves their lives? mark scout, devon and cobel miscalculated by assuming mark s. would be okay with dying. mark scout in particular fucked up by assuming his innie had no agency from the very beginning of those recordings - because even after all that mark s. did for them (he is the reason mark scout even found out gemma was still alive!), they still don’t see innies as people.
i also don’t think he was trying to screw over mark scout or say fuck you to him and gemma and their happy ending at all; he was just exercising HIS autonomy and making the decision HE wanted to make. to buy himself more time with the one life he’s been given.
his allegiance was also rightfully with the very few people he knew and loved. he had no allegiance to mark scout and gemma, but still did an incredibly kind thing by helping gemma escape - because he is a kind person. but assuming he’s kind enough to just choose to give up his own life without a fight is ridiculous.
mark s. has had literally had no control or say in his entire fucking life. him running in the hallway with helly, towards what they believe to be certain death - it’s cathartic. it was the right decision. i don’t think it came out of nowhere at all; they have been setting the stage for this all season, with the very first hint being in the new opening sequence where helly and gemma glitch and blur together.
what does it mean to be human? mark s. just told you
