(Adapted slightly from this Tumblr post I wrote)
Viola: Hey, Olivia… I’m actually a girl pretending to be a guy.
Olivia: Oh yeah, I knew that all along. I just pretended you were a boy because it’s way more socially acceptable for a woman to fall in love with a man. 😉
Viola: Wait, you’re still in love with me?
Olivia: Of course!
Viola: Actually… I think I’m in love with you too! Wanna get married in secret?
Olivia: Heck yeah!! Oh, and by the way, Maria—you shouldn’t marry Sir Toby because he’s a total jerk.
Maria: That’s a good idea! Why didn’t I think of that before? Oh, and I should also go apologize to Malvolio.
Orsino: O, Olivia, my love… where are you going?
Olivia: To go get married to a girl!! 😀
Orsino: Hang on, you’re a lesbian?! Never mind, I give up trying to woo you—it’s never gonna happen. 😛
Sebastian: Hey, Viola! It’s good to see you again! Can me and my boyfriend Antonio join in your super-duper secret same-sex wedding?
Viola: Sure thing! 😀
And they all lived happily ever after. XD
