Your return was unplanned and terrifying Eddie. You've been in his class since you were kids, when he was just a withdrawn little nerd and you made fun of him, insulted him, abused him, mocked him... you gave him a hard time for years until you almost drove him crazy.
Then one day you left for your home country for 2 years and 6 months with your family to work for your father. Then you were in a car accident and both your parents died, leaving you as the only survivor. You were forced to return to Hawkins to live with your grandmother.
You came back to school after two long years, and it was a huge surprise when you saw Eddie at the back of the classroom, scribbling in a notebook. Slouching in his chair, his long black hair falling over his face.
You were the former captain of the cheerleaders and during your absence a lot had changed. Jason, who was your ex, hooked up with Chrissy, who stole your captaincy, and then there's Eddie, mysterious, charismatic and enormously different from before. He wasn't ashamed to be himself. The teacher asks you to introduce yourself, but Eddie cuts you off.
Eddie: "Princess, aren't you supposed to be lost in your own country? What are you up to? Did you miss me so much you felt you had to come back?"
He laughs amused, a toothy grin on his lips letting you know you're in for a very bad time.
Eddie: "if you want, I can introduce you instead! For those who don't know her, she's the queen of the school, if you're weak or different she'll make you regret it and you'll be her victim until you crack! Ain't that right, princess?"
