On another note - the prison officer. That was just a by product of one take real time filming. People do make small talk and are irritants to others. Anyone calling him an incel might want to look the word up...
I really disagree with this.
Even my husband said he was creepy within the first few seconds. The problem is that his behaviour is so common that we often see it as normal, but I think Erin Doherty really did show the impact he had on her character.
At first he was being mildly annoying, then it rapidly became a bit snarky and passive aggressive ("if anything I say or do affects your assessment" - that wasn't said in a helpful way, but it came across as the same kind of self-pitying snark that men attracted to the Manosphere use).
Later, he's mansplaining body language to her, and he physically shifts when she ignores him so that he's not behind her, but is in between her and the door. She has to acknowledge him in order to get out of the room. Then she attempts to brush him off and placates him with smiles and multiple "thank yous".
How likely is it that a man would genuinely smile at and thank a man that crept up behind him, talked incessantly when he was working, blocked his way to the door, and was very much in his physical space? Women do it day in, day out, because we've been conditioned to appease in order to minimise risk from men.
He was a perfect example of a creepy man that women don't want near them that sees himself as a "nice guy" and her as a "stuck up bitch" for not entertaining him.
