So, her vote for Marshmellow was a strategic choice, since Marsh was so popular. She thought that, if a vote came down to her and someone else, Marshmallow was who she was least likely to beat, so voted for her!
Not entirely something that couldn't be gauged from the original line ('Marshmellow is mean~' emphasising a flaw of Marsh's directly to the audience via confessional) but a neat part of them making Taco a bit more... not obvious, but... a bit more transparent, if that's the right word, in this reality.
I do think I prefer the less transparent version, solely because I adore the idea of Taco being a (near) perfect actor that slowly descends into breaking apart from all the emotions she pretends she doesn't have, but I do think this version is interesting as well!! :]
