In Season 2, the main characters have to adjust to their new situation - the rule of werewolves and the potential danger. Although Klaus and Hayley swear to make New Orleans a safe place for their daughter, they also need to overcome their inner demons. After her daughter is gone, Hayley will become very angry and depressed, while Klaus, who needs power and energy at the moment, is weakened by the moonlightring. Elijah will feel isolated from his family and seek revenge on Francesca and her werewolfs, while also forming a connection with Marcel and the vampires who rule Marcel. Despite the danger, Cami resumes her studies and wants to reclaim the life she had before she met Klaus. However, the werewolves are not the only enemy. What Klaus and Elijah did not expect is that their evil parents have returned. Although Mikael is controlled by Davina, he is determined to kill Klaus, even if he needs to break free of Davina's control first. Their mother Esther is motivated by her own abnormal love for her children. She has a sinister plan - to make her family complete. This plan will cause great suffering to Klaus and Elijah and everyone they love.
