why does rashta refer to herself in third person? it makes her seem even more peculiar

It’s baby talk, she’s been doing it since the start. It’s to make herself appear more naive and innocent.

Because she’s too dumb to live

good lord she gives me the ick so severely

in the novel she says that since everyone refers to her by insulting her and calling her awful names, she tought that she should be the one to call herself by her own name kindly.
