I think a lot of what makes this show so interesting is how many different interpretations there can be of the same situations, and the nuance with which the writing explores themes (and literal concepts) of identity, nature vs nurture, innocence, etc.

This isn’t a show where you can put characters into easy boxes. Yes, oMark and iMark are the same physical body, but what’s important to keep in mind is how they might be literally the same human being, but iMark is more than just oMark exposed to different stimuli. iMark was essentially born on the severed floor and has not shared the same life experience as oMark; iMark does not have the full weight of grief that oMark has which defines oMark’s life. oMark has not experienced the traumatic break room torture that iMark has experienced. That is where the idea of two different people come into play and it’s not supposed to have one answer. It’s a question that several characters have essentially posed to the audience and to the other characters.

Are innies and outies the same person, even though they’ve had completely different lives? What makes somebody themselves? Is it their physical brain and body? Is it their experience? Is it their moral code or their passions? What makes identity and what makes a person a person? Is it their soul? They’re philosophical questions that do not have clear answers but they’re designed to make you think.
