Warning: Spoilers for the Bates Motel episode "Marion" follow... With this week's episode, "Marion," Bates Motel sealed off its two-part Psycho arc, giving us a terrific and terrifying new spin in the iconic shower scene from the Hitchcock film. Marion Crane, played by superstar Rihanna here, survived her stay at Norman's rest stop while Austin Nichols (The Walking Dead) fell to multiple stab wounds and the loathsome character of Sam Loomis was no more. On top of this, Norman discovered some startling new facts about his "Norma" personality - most notably, where she'd been spending her nights.
