On the midseason finale of "Revenge," old flames reemerged and tempers flared.

In "Hatred," Daniel (Joshua Bowman) moves his ex, Sara (Annabelle Stephenson), into Grayson Manor to anger Emily (Emily VanCamp), and Conrad's first wife (Gail O'Grady) makes a reappearance.

Nolan (Gabriel Mann) gets back at Patrick (Justin Hartley) for assaulting and robbing him by revealing to him his father's identity, and telling him that his father was turned away-- as per Victoria's (Madeleine Stowe) instructions--from the orphanage when he came to take Patrick back. But Victoria eventually reveals to Patrick that his father raped and stalked her, so she gave Patrick up for adoption to protect him.

Meanwhile, Margaux (Karine Vanasse) learns that Conard (Henry Czerny) put false content in Voulez so he could sue the magazine for libel. Conrad is angry at his son for costing him Lydia, so he wants the editor to fire him and make him her new partner.

Niko (Stephanie Jacobsen) wants Aiden's (Barry Sloane) help in avenging her father's death, and moves into Nolan's house. Nolan then makes up a story that casts Declan's killer as Takeda's killer to make her leave the Hamptons on a quest for the murderer. But before she leaves, she finds the murder weapon that was used to kill her father in Aiden's bedroom.

Daniel's idea to move Sara into Grayson Manor was not the best idea. He flaunts the affair in Emily's face, prompting Emily to call in Sara's mother, who disowned Sara after she refused to stop seeing her married boyfriend. Sara then decides to stop seeing Daniel and be reunited with her family. 

Daniel, who is furious, gets violent with Emily and tells her: "Sterilizing you was my gift to the universe."

Emily also suffers blackouts throughout the episode, which is a side effect of her head injury. It results in her unexpectedly showing up at Nolan's, and later waking up in Conrad's bed. Conrad even compliments her on the night they spent together.

On the next episode, "Payback," Aiden could be in big trouble, and Emily may conspire with Conrad. 

When "Revenge" returns, Olivier Martinez will also debut as Pascal LeMarchal, Margaux's media mogul father. The character has a romantic history with Victoria. 

Check out the preview for "Payback," which airs Sunday, March 9 at 10 p.m. on ABC.
