Since the death of Daniel Grayson, Margaux has made it her goal to exact revenge on Emily. Victoria had a hand in the plot but until now, Margaux does not know the truth behind Emily's actions. She is relentless and she wants to hit her target where it will hurt the most. 

Jack Porter is someone very dear to Emily and was once very dear to Margaux, too. However, the latter has no problem using him as a ploy to rip Emily's heart wide open. The vengeful woman managed to convince the police to arrest him for driving under the influence, which is something she has staged from the beginning. Now, he is in deep trouble and Emily will try to save him. 

Episode 17 is titled "Loss" and the official synopsis goes: "As Emily fights to clear Jack's name in and out of court, newlyweds Nolan and Louise receive a visit from Officer Ben Hunter." 

In the sneak peek for the upcoming episode, Emily tells her father David that she's done seeing her friends go through terrible things. Seeing the look on her face, Margaux should be hiding now. However, in the episode trailer, Margaux gets hit by a speeding taxi cab and the look on Emily's face shows that she's not the one behind it. 

As for the newlyweds Nolan and Louise, Ben pays them a visit but he doesn't appear to be a bearer of good news. The visit could be about the death of Louise's brother Lyman, whom she actually pushed off a cliff after an intense fight. Does Ben know anything about it? 

Could the next episode title be foretelling of what will happen to one of the major characters? Could "Loss" mean that Margaux will die after the hit or could this mean loss for Emily as she cannot save Jack? 

"Revenge" will air "Loss" on Sunday, March 22, on ABC.
