Bailey (Chandra Wilson) announces plans to start a free clinic, and Izzie (Katherine Heigl) has the money to make this dream come true--provided that the clinic is named after the late Denny Duquette. Meanwhile, Cristina (Ellen Pompeo) receives a marriage proposal; George (T.R. Knight) expresses his grief over his father's death in a truly unique fashion, much to the delight of Callie (Sara Ramirez); and Addison (Kate Walsh) and Alex (Justin Chambers) take great pains to avoid each other. Also, the surgeons become emotionally involved in the plight of Jillian Miller (Jessica Stroup), a young Amish cancer patient torn between her strict parents and her "shunned" best friend (Rachel Boston). ~ Hal Erickson, Rovi
