i headcanon miranda as someone who struggles with english, which further adds to how nervous she is during social interactions. i also think she’d have a heavy german accent.
this would further explain why marie is so comforting to her; he can speak english better than she can and helps her with words she doesn’t know how to say
legend has it even inspector howard link helped miranda improve her pronunciation during downtime on missions – no one can tell he has an accent except when he starts yelling at allen walker
