|Episode(s)||5.07 The Curious Case of Dean Winchester|
Patrick is a 900-year-old witch who plays poker with people, gambling with years of their life. When he takes 25-years from Bobby, Dean plays and donates 25 of his own years to save the older hunter, and loses an additional 25.
Lia, Patrick's partner, gives them a reversal spell. As Dean and Bobby undertake to do it, Sam stalls Patrick by playing cards against him. When the spell fails, Dean's life is in the balance as Sam plays for real. Finally winning. Lia tells Patrick she wants to die, having long outlived her daughter, and they play a hand in which she loses all her years.
