So Long, Farewell

S4 E8: With Hannah (recurring guest star SARAH DREW) leaving for Minnesota in a few days with her mother, Diane (recurring guest star JAYNE BROOK), Bright and Amy find themselves taking Hannah's pending departure harder than even they expected. Jake (recurring guest star SCOTT WOLF) sets out on a high-risk bike trip with his friend Cliff (SIMON REX) that takes a near fatal turn. Drs. Brown and Abbott uncharacteristically decide to go skydiving after hearing of Jake's daredevil ways. And Reid (recurring guest star JUSTIN BALDONI) keeps his promise to Ephram and stops pursuing Amy, leaving her feeling all the more lonely.
