I 100% don’t think nokys tears are fake. I think she went into the house probably very sure of herself, confident, probably was used to being admired and never struggling to make friends. What’s actually happened is the opposite, she’s been picked on, had her character attacked constantly, I expect her self esteem is in bits at this point, no wonder she is tearful. I do agree we get a very edited version of her and she’s not maybe being completely true to herself but the experience has been awful for her, she would probably be better off walking for her own sake which is so SO sad.
