*Karen Wheeler Character Poster
In season 4 every main character has a poster (Ex. Joyce, hopper and Murray = Russia,) Karen was not a main character in season 4 yet still had a poster with the creel house. She was never in the creel house.
They are the same age
Alice Creel was born in 1944, and Karen Wheeler was born from 1944-1946 which makes her the same age.
She walks around like she knows something
She's the only mother that went to Joyce's house after Will went missing. In season 4 they zoomed on her face when all of the parents.
