In the second episode of "The Originals" season 4, viewers will see Klaus (Joseph Morgan) reunited with Camille O'Connell (Leah Pipes).

Based on the trailer for the episode, Cami will appear before her former love interest as a hallucination. "You are the reason your family is alive," Cami tells Klaus before adding, "and now they've woken up."

"Klaus is going to be experiencing this terrible torment," executive producer Michael Narducci told TV Line, "and one of the moments of solace and relief that he gets is conjuring this memory of this person who meant so, so much to him."

The CW recently launched photos of the upcoming episode, titled "No Quarter," giving fans a sneak peek of Rebekah (Claire Holt) and Marcel's (Charles Michael Davis) reunion. Narducci also revealed that Holt will be appearing in a number of episodes in the current season, particularly in about half of it. According to the executive, "Rebekah has an incredible journey to go on."

One of the photos that the network teased features Rebekah with her brother Elijah (Daniel Gillies). To recap, Hayley (Phoebe Tonkin) finally found a cure for his werewolf bite, which is why he is back in the game. The moment the family was reunited, Elijah, along with his siblings, hatched a plan to save their brother Klaus, who is still being held captive by New Orleans' new leader Marcel.

Marcel, however, seems to have anticipated the return of the Mikaelsons. According to Davis, Marcel is still incapable of disposing the vampire that sired him, but he has not forgiven the original family for the pain they have bestowed upon him or onto his friends. Elsewhere in the upcoming episode, Elijah will face off with Marcel. Either one of them could easily end up dead.

"The Originals" season 4 airs Fridays at 8 p.m. EDT on The CW.
