Lorna remains upbeat in the face of her separation from Tom, hoping that a sexy new look will rekindle his passion. But he is still very much in love with Izzie, and his feelings are too strong to ignore. After a student, Zak, repeatedly shows up late for school, Andrew suspects drug use, but upon visiting Zak at home, Andrew and Kim discover that Zak's mother has Huntington's disease, and he needs support rather than condemnation. Meanwhile, sticking to her pact with Donte, Chlo insists that she was driving on the night of the crash, but neither the police nor Izzie believe her. Chlo resorts to desperate measures, stealing her father's van to prove that she can drive. And fearing for her job, Steph fakes a break-in to her classroom and disposes of the incriminating coursework.
