Few things I noticed about the stage door TikTok, specifically the one about the guy wanting to know her next role.
If it did happen, I'd imagine that story has been heavily embellished. I would guess most actors get similar questions thrown at them at stage door. To make hers stand out and seem 'worse' she went down the route of the person being aggressive and unreasonable. For sympathy, attention, lols...who knows? She does appear to like playing the victim.
If it did actually play out that way, then her response was immature and could go some way in explaining why she moans so much. She makes life difficult for herself. Instead of trying to explain everything about contracts and secrets and her parents, why not make a little joke and lightly brush the guy off, ask him if he wants a selfie and move on to the next person. Why get too deep? A more seasoned, rational person would try to diffuse the situation than overexplain and prove themself right.
And finally, she's just not a good actor. I've seen "normal people" ie. People who dont get paid to be on stage, perform better on TikTok.
