Who is Mary Sue and how many languages does she character speak?

Inmy defense the character is a robot, she is made to help people and therefore has to speak multiple languages.

1-2.

Kitty speaks English because it's her main language, and Spanish because she has a few Spanish roots in her family. Her spanish Aunt, Aunt Matilda, who's latina, taught her and her siblings Spanish two years ago. Since then, they've been practicing.
