Reading through the character descriptions, everyone sounds like a type we've seen before, the loyal guard, the by the book lieutenant, the scared new convict. None of that is bad exactly, these archetypes exist because they work well in prison stories, but I hope the writing gives them small twists so they don't feel copy pasted from every other prison show ever made. The maternal bond angle with Iris caught my attention the most out of everyone listed, that kind of relationship usually adds real emotional weight to shows like this instead of just action and escape planning.
