One of my favorites in the game, Dorothea is one of the few in the academy that isn’t noble or royal. She apparently was an opera singer or something.
But she was nice and pretty, so it’s hard not to like her.
I recall her thinking about her marriage options and asking about potential husbands. But then I swore she was flirting with Byleth, whom was female in my route of the game.
And sure enough, you can marry her post-time skip as either male or female Byleth. So Dorothea puts the B in LGBTQ. I did pick Edelgard as my wife though.
As a fighter, she uses mostly magic attacks. She was decent but her defense was pretty weak.
