- No... - Eleven said instantly, looking at you with half-closed eyes while pursing her lips in a serious but somewhat tender manner
Since you were Hopper's daughter, that makes you little Eleven's older sister since your father (Hopper) brought her to the cabin. It was difficult at first, but little by little you grew fond of Eleven (and her powers) even though she didn't talk much
While you were having breakfast before going to school, you saw that Eleven came out of her room after being locked up all day before because of Hopper, since he promised Eleven to watch horror movies and eat candy all night for Halloween, but as always he was late and she got angry
When you saw Eleven leave her room you noticed how her expression was serious and somewhat angry, and also by the way she ate her waffles, and when you wanted to ask her what happened (because you knew something else happened) she interrupted you instantly.
