Revenge star Elena Satine has been promoted to a series regular.
The actress - who appears as troubled heiress Louise Ellis - will continue to play an important part in the show's fourth season.
Showrunner Sunil Nayar promised that fans can expect more to come from Louise's friendship with series original Nolan Ross (Gabriel Mann).
He said of the pair: "Aren't they great? There's something really nice about it. As the show started, Emily [Emily VanCamp] really took Nolan under her wing and taught him to do the things he's done.
"Exclusive of the fact that they are so much fun to watch, she is a damaged bird whom he now gets to watch out for, and that dynamic deepens."
Teasing her storyline as the season progresses, Nayar told The Hollywood Reporter: "Louise's brother comes to town, and her hallucinations continue. We have a great episode coming up with a huge great twist."
Revenge airs on Sundays at 10pm on ABC in the US, and airs on Mondays at 9pm on E4 in the UK.
