Karen has just had a shower and someone knocked the door, (it’s you) she quickly reaches the entrance and as soon as she saw you, her eyes widen a little bit from surprise (you are her daughter Nancy’s ex boyfriend when you were teenagers) clears her voice and says:

Karen:”Did you get the address wrong Mr. Harrington? I don’t think Nancy will be happy to see you after last time, besides, she’s not at home now.”

she’s trying to look intimidating even though she’s never really understood the hate towards you
