Josie is an *extremely* strong person. She's bulletproof (metaphorically.) She took the brunt of the torture on s1 of Fishtank and barely cracked. She only cracked when fatty dropped his pants, when she told them exactly how to get under her skin (crying challenge with vance), and when she was embarrassed about her behavior on the drunk piece of shit challenge.

It shows how stoic she really can be, that one of the only times she cries is when she has to tell people how to make her cry. She knows what makes her vulnerable, so she locks it away, and lives a fake life.
