It only natural she wants to leave, he knows she's a girl. How's she supposed to spend all her life pretending to be a man, hiding her period, and dyeing her hair all the time,. She didn't want that, that's what her mother made her do.
I didn't like this couple precisely because she works for him. She's lived her whole life under his thumb and I honestly would love to see Elijah go out into the world and interact with new people and follow her dream no matter the difficulty.
