As a taped message from a great-grandchild plays, Allison quietly passes away in a nursing home on the series finale of 'Medium' (Fri., 8PM ET on CBS). Joe, who died 41 years earlier in a plane crash, is patiently waiting as she enters the afterlife.
Earlier in the episode, Allison attempted to convince herself during an extended dream sequence that Joe wasn't dead. But, alas, her husband in fact died while returning from a business trip to Hawaii.
But now, as Allison succumbs to old age, the two are reunited "from now until the end of time."
