I keep thinking about how Olivia literally falls passionately in love with another woman onstage. Like yeah I absolutely headcanon Viola as nonbinary or transmasc too but as far as Shakespeare was concerned she's a woman* and he just wrote another woman declaring her heartfelt, undoubtedly romantic love for her. That's absolutely wild. Outside of Achilles and Patroclus, who aren't Shakespeare's own characters, it's technically the only case of Canon Canon™ romantic love between same sex characters in Shakespeare (though sadly Viola does not return the feeling in canon.)

*of course she always would've been played by a male actor and the crossdressing comedies have fun with that, but the same goes for every female character in Shakespeare so...
