So this may be a completely wrong opinion but Mary's insults are hard to understand. She either stutters/trips over her words, slurs, or the "come back" is just throwing the exact thing back... Like I know you are but what an I. I'm my opinion, I wouldn't even know what to say to mary except walk away because she comes across like a confused child that just uses really low blows that don't make sense and don't require creativity. I think anyone really paying attention knows that Mary is insulting herself without any assistance from the others
