Alex is haggling with Meredith over making repairs to her house, as he's set on buying it. The two of them bicker about this while working on a patient. A young man named Brian comes in with severe abdominal pains. A mass is found on his liver, but the kid is also taking steroids. This is a shock to his parents. Later, the mass on Brian's liver is revealed to be cancer. Alex and Meredith remove it, but there's a chance of reoccurrence if the kid keeps using steroids. If only his parents had known about this sooner.
Alex tells Meredith that he's looking to grow up. That's why he wants the house. Meredith lets him know that the reason she doesn't want to make the repairs he's requesting is because the marks and scratches he's listed have meanings behind them. The chips on the ceiling are from the Christmas tree they got their first intern year. There are scratch marks on the door jams for both Zola and herself when she was little. These two finally reach a deal. Alex has a new house. He also has a new roommate in Cristina.
