A PlotEllie accidentally spends the night with Sean in his pad. While frantically rushing out the door not to get caught by her mom, Sean asks her to move in with him. Ellie just can't leave her mom in her state, and the upcoming faculty/parent open house isn't alleviating her stress. At the open house. Ellie's mom basically makes an ass of herself in front of Ashley's gay dad and partner and Mr. Simpson and confronts Sean. Later that night, she nearly burns down the house in a drunken stupor. The house isn't fit to live in at the moment and Ellie convinces her mom to let her stay over with Ashley, but she goes to stay with Sean.
Sean and Ellie throw a house party and everything's cool until Ellie's mom shows up and drags Ellie out the party and slaps Sean in the face. When they arrive at their house, Ellie is furious and confronts her mother — and reveals for the first time to her that she cuts herself due to her drinking. Ellie's mother is distraught, but she realizes that she has to do. She goes to rehab, and Ellie is allowed to live with Sean. And she buys him a gift — a ferret!
