Yup, body language in the lift scene is very off - comes in glaring/scowling and arranges themself very close/shoulder to shoulder with the woman (do people still do this since COVID?), the mirror behind them emphasizing the trans identifying individuals broad shoulders and height.
Just like the 'not cool girl/bystander' train/coffee/suicide ads where woman were encouraged to approach unwell men on public transport, evil lift woman is dressed as a frumpy dumpy stereotype, with her high necked uptight blouse, untucked at the back, and round shouldered grey cardigan, poor makeup, clearly not performing 'feminine' as well as the trans individual, and also deficient in her female socialisation in not being a good little support human. The message is you dont want to be like her, older, unfashionable, overweight, not confident.
But the last minute, nervous bolt for the doors, without a derisory look or word to the male who has just made her uncomfortable, suggest fear of being in an enclosed space with a male rather than an act of aggression. Who really felt unsafe in this scenario - it seems a bit of an own goal advert?
