ABC's Revenge circles around Emily Thorne's (Emily Vancamp) plot to avenge her father's death and take out those she believes responsible for it, but some viewers cannot help but lose focus of the storyline when the male stars come on screen.

Actor Justin Hartley is the latest addition to the lineup of good looking me on the series. He joined the season 3 cast as Victoria Grayson's long-lost son Patrick Harper. He previously starred in the television series' Smallville, Heart of Dixie and Emily Owens M.D., and the soap opera Passions.

The Graysons at first did not welcome Victoria's son into the family with open arms but time will tell if they have a change of heart. Hartley is signed on to star in the show throughout season 3.

Gabriel Mann's role on Revenge is Emily's trusted best friend and computer genius Nolan Ross. While many of the other men in Emily's life have come and gone, Nolan remained loyal to helping Emily carry out her scheming. He was also close to her father, David Clarke, and promised him he would look out of Emily.

Nick Wechsler's character, Jack Porter, thought he was married to his childhood lover Amanda Clarke up until the season 3 finale, where Emily revealed that she is the real Amanda. The two have had a rollar coaster relationship from the start and deep down Emily still loves Jack, but now he hates that she is lying to everyone about who she is. He is also disgusted by her determination to cause harm to people, even if it is to avenge her father.

Emily declined Aidan Mathis' offer to run away with him in season 3 because she loves Jack.

Barry Sloane plays Emily's once lover, now scorned enemy, Aidan Mathis. He told her she is too consumed with her plot of getting revenge and though he loved her, he could not wait around for her any longer. He left town in the season 3 finale and when season 4 began, he returned to team up with Victoria Grayson to take down Emily and uncover all her lies.

Aidan and Emily were trained by the same mentor, Takeda, and he is one of the few people at the start of season 4 who knows her true identity and purpose for being in the Hamptons.

Joshua Bowman's character, Daniel Grayson, is Emily's character at the start of season 3. The couple have been engaged before and it has yet to be seen if they will tie the knot, especially since Victoria despises Emily. Daniel has tried to move out of his father's shadow and is now the publisher of a magazine instead of working at Grayson Global like he did in the past. He does not question Emily's motives as much as others in his family do, and is seemingly unaware of her desire to make Conrad Grayson's life miserable.

Revenge airs Sundays on ABC.AT 9/8 p.m. Central.
