Revenge is moving towards a potentially finite ending to the Grayson/Clarke feud but the key players shouldn't take their eyes off Louise in the process.

Nolan and Louise's sham marriage is on the rocks (no surprises there), and Ross' fake bride is not taking the news particularly well. A snake in the grass once more, Louise will make some shocking decisions before season 4 comes to a close in "Two Graves."

"You're going to see her take a very interesting turn," showrunner Sunil Nayar explained, according to TV Line. "She'll start to question her fidelities to everybody she's met on the show and make some very dramatic decisions as we head towards the finale."

Long acquainted with the sting of betrayal, Louise will find herself in a familiar state of mind following the discovery of Nolan's USB of every dirty, deceitful, and criminal act Emily Thorne ever perpetrated in the Long Island town. Louise's actions will take on a new burst of energy now that she has seen the material that makes up every judges' daydreams.

"Betrayal is a touchstone for her, and she's learned a lot of new facts she didn't know before - especially things that her husband didn't tell her, like who Amanda Clarke actually was," Nayar teased.

So which side of the Dumas-esque conflict will Louise land on? It looks like she is ready to fall into the dangerous embrace of Team Victoria but viewers will have to tune in to the season's (and possibly the series') final episodes to find out her true motives.
