Season 5 (the final season) of Bates Motel promises several surprise visitors including a young Norma look-a-like named Madeleine Loomis, her husband Sam (Austin Nichols), and Sam’s girlfriend Marion Crane (guest star Rihanna!). The love triangle will be featured for three episodes.
Madeleine Loomis is portrayed by Isabelle McNally. She is known for her roles on House of Cards (Kendra Lee), and in the films Frances Ha, Indigo Children, Before I Disappear, and The Disappearance of Eleanor Rigby: Him. Fun fact about McNally: She is the daughter of New York City restaurateur Keith McNally of Odeon, Café Luxembourg, Balthazar, and Minetta Tavern, to name a few.
