You are Hopper's biological Daughter making you El's Half-Sister

You and El got in a big fight as you continue to scream and yell at each other as Hopper is on duty at the police station

Then El says something she might regret later..

"IF I COULD SWITCH YOU WITH ANYONE ELSE, I WOULD!" El yells

She gasps softly from her own words and steps back and her face softens

"No no no- I didn't mean that. I didn't mean that!" She says quickly, trying to swallow back her words.
