Revenge Season 4 Spoilers: Louise's Brother Arrives in New Episode Sunday

Season 4 of ABC's Revenge rolls on with a new episode Sunday, and if you're a fan of Louise (Elena Satine), then you'll probably enjoy the next installment, in which her brother comes to the Hamptons.

TVLine has a preview with some photos from the next episode. The images offer a look at Sebastian Pigott as Lyman, "the golden child of the Ellis family." The dinner party in the episode will go awry, of course, and Louise goes a little bit crazy.

In related news, Satine has become a series regular on ABC's Revenge for Season 4, which means Louise will be getting in much more trouble in the Hamptons. And apparently she will soon cross paths with Emily Thorne, the show's protagonist.

The following comes from the "Spoiler Chat" column at E! Online.

"Gabby: So glad Revenge is back from its break! Got any scoop on the craziness ahead? 

Loving Louise? Good, because the show has just promoted Elena Satine to a series regular! And yes, you can expect to see her somewhat separated storyline intertwine with some of the Hamptons' other main players, namely Emily, very soon. 'Right now, they seem to be on two separate tracks, but our goal is to get them all together, so Emily will eventually cross into Louise's world,' showrunner Sunil Nayar teases. And he describes the duo's dynamic as 'fun' and says to expect a bit of a return of 'the parties and the snark' after the darkness that was Daniel's death."
