Fox's promo department touting the episode as "The One that Changes Everything," Meat Loaf says that's "a hard one to answer without giving anything away." He can reveal, though, that he worked with Laurie, Jennifer Morrison and two other main characters, and that "the whole storyline is about redemption." 福克斯广告片部吹捧这一集(下一集5-20)是“改变了一切的一集”,Meat Loaf(主要病人演员)说“回答而不泄露任何剧情是件艰苦的事”。尽管如此,他揭示与Laurie(House),Jennifer Morrison(Cameron)还有其他两位主要角色一起出现,并且整个故事情节关于“redemption(赎回;偿还;拯救;履行)”。
