Dallas fans will soon have to say goodbye to Larry Hagman's J.R. — but they'll meet two new members of the Ewing and Ramos clans. Emma Bell (formerly Andrea's sister, Amy, on The Walking Dead) plays Bobby Ewing's well-bred stepdaughter Emma and makes her debut in the January 28 season premiere. She appears with Hagman in tense courtroom scenes he completed days before his death. "He was very welcoming to me," she says. "And I was like a giggly girl my first day working with Patrick Duffy, who I grew up watching on Step by Step."
Kuno Becker will stir up trouble as Elena's brother, Andres (nickname: Drew), who was raised on Southfork with John Ross and Christopher and moves into his sister's cottage. "He comes back from Afghanistan with a lot of anger and wants to drill his late father's land," says Becker, who played a serial killer on CSI: Miami's final season. Drew will go to extreme measures to get what he wants. "I've had to do a lot of training with firearms, and I get to shoot in a big action scene, but I can't reveal at what or who."
