Speaking with TUDUM, Mitchell discussed the influences on her character and her portrayal's impact on blind people: 

“She’s influenced by a combination of my aunties and my grandmothers, their attitudes, that rambunctious, outgoing, outspoken personality. The fact that there’s a desire to be inclusive in casting, that there’s actually a demand for that authenticity. It allows the world to see blind people for who they really are and how we're just as normal as everyone else.”
