北京时间9月25日，ABC电视台重磅医务剧将以两小时特别篇回到我们的视线，上一季结尾留下的Izzie和George的去留问题将在回归篇中一一解答。感谢KatherineHeigl的直言，我们已经大概得知剧中这两位主要人物的命运。Izzie将会幸存下来，而George将告别观众。而且因为TRKnight的合同问题，George可能将不会再以新镜头出现在第六季中，开篇也仅仅将以一具棺材代替他的存在。ABC电视台也确认George的扮演者TR Knight将不会成为第六季的常规演员，与之相反的是扮演儿科医生的Arizona Robbins的JessicaCapshaw将有幸成为第六季的常规演员。可以预见，其与剧中另一主要角色Callie的同性恋情的戏份也将加长。
