'Revenge' Season 3 Spoilers: Emily Thorne's Love Life 'Gets Out of Control' as She Goes on Mission with Jack [VIDEO & PHOTOS]

More than a clichéd love triangle, Revenge's Emily Thorne must deal with three men making her life that much more difficult in Sunday's new episode of the ABC series.

A promotional video for the Oct. 20 episode, titled Mercy, shows Emily (Emily VanCamp) getting into a heated discussion with her fiance, facing her scorned true love who wants answers and figuring out what to do with her ex-boyfriend who returned to The Hamptons for her.

"Revenge can be tough on your love life," the video's voiceover says.

Daniel Grayson (Joshua Bowman) is shown telling his fiance "you walk out that door and I'm not gonna be here when you get back." Emily grabs her jacket to leave their home and tells him "I thought you were better but you're just as wrapped up in your family's lies."

Aiden Mathis (Barry Sloane), who recently returned to The Hamptons, wants back into Emily's life and tells her "I came back here to help you finish this." He was seen coming to Nolan Ross' (Gabriel Mann) house party with Victoria Grayson (Madeleine Stowe) but Aiden still has feelings for Emily and a still shot from the episode shows him holding her hand. He is also shown in another still shot topless and getting close with another woman.

Jack Porter (Nick Wechsler) is also not giving Emily an easy time. He meets up with her in his bar and says "if I'm in danger I'd like to know," probing Emily to reveal more than she might want to. She then instills enough trust in him to go with him on a mission, but things do not go so smoothly. ABC noted about them teaming up, "When Emily's biggest takedown yet crashes and burns, she must rely on help from an unlikely source to investigate what went wrong."

There is also a heated confrontation between Aiden and Jack that takes place in Sunday's episode.

Season 3 of Revenge airs Sundays at 9/8 p.m. ET on ABC.
