We know that women work and do other things. We know that they exist for much better things than just keeping their eyes on a man that they love. Depending on the century they come from, she probably doesn't mind watching him work. She doesn't mind just existing for him. It's what she has at the time. Why not live in that moment of watching a loved one? She never knows when he'll have to fight off again and maybe he won't return. It's a book, Finn. It's not meant to make sense. It's meant for entertainment. They can make sense at times. But fiction, not all the time.
