Personally I like how she drops the accent and rhythmic tone of voice when she’s proper pissed. Cuts deeper as to me it shows it’s a coping mechanism for Zecora. That perhaps she does it for her own sake rather than purposely trying to be cryptic and vague in her speech. Adds another layer to her character instead of it being seen as “out of character”. Everyone is different and everyone has a means to cope in a world where they’ve suffered great loss or hardship that’s unbeknownst to others. I think Zecora just couldn’t take the bs AJ was spouting which triggered her inner insecurities and lashed out unintentionally. I’ve done the same many times. I had a way of conducting myself while in school and work, I was very timid and very quiet most of the time. But I still spoke with respect to everyone. But when people acted badly towards me which was reminiscent f past trauma I’ve suffered, my entire disposition and demeanour changed and people get frightened of me. They never expected me to say the things I did or do the things I would normally never do and thought of me as “completely out of character”.

I guess I relate to Zecora in a way, cause there’s only so much you can take before you drop the act and show who you really are underneath the mask of insecurity.
