‘Grey’s Anatomy’ Texas-Set Spinoff Casts Karla Souza

She previously starred in ShondaLand’s ‘How to Get Away With Murder.’. Grey’s Anatomy fans might have to wait a bit longer than they might’ve hoped for the new Texas-set spinoff to arrive on ABC, but what we don’t have to wait on is some casting news. Deadline reports that Karla Souza will lead the cast of the new series as Carolina “Lina” Hall, a character described as “a haunted and cynical doctor in her 40s who runs a medical center in a small town in West Texas.”
