hear me out: donut actually sitting down and learning more spanish?
1, it would break up his haha oblivious gay stereotype, n 2 he could communicate w lopez (the person he striaght up confessed his love to) better!! what’s not to love?
building off of that: he can still make funny mistakes (he’s only human), and he can still translate lopez wrong, even on purpose! lopez likes his ability to secretly shit talk, so donut can make something up, and everyone would still take donuts word for granted.
nothing really changes, but donut grows as a character and he and lopez bond, it’s a win-win
