After several mentions by Louise, Deadline reports Lyman Ellis will eventual crop up in the form of Pacific Rim's Sebastian Pigott.

While some viewers were hesitant to believe Louise even had a brother, particularly after realizing that her mother was far from corporeal, it seems Mr. Ellis is most definitely real. A manipulative politician, TV Line reports that Lyman will (unsurprisingly) have ulterior motives.

The newest addition to the Hamptons may be better suited for a role in One Flew Over the Cuckoo's Nest, however. Considering how off her rocker his sister is, Lyman may have also received a dose of the family's crazy gene.

In the meantime, Louise is busying herself devising a way to take down the one-time Queen of the Hamptons. Victoria's (Madeleine Stowe) asylum buddy wormed her way into Daniel (Joshua Bowman) and Margaux (Karine Vanasse) lives, spreading mayhem at a remarkable speed, and Louise spent "Contact" cozying up to a distressed Nolan (Gabriel Mann). As she works her way through the Hamptons, who else will Louise trick in her search for revenge?
