The relationship between Klaus and Elijah improved during the course of second season. As the duo had to face the Guerrera werewolves and the witches faction led by Genevieve. The brothers came close to each other and started trusting each other more. But their relationship became worse than ever when Elijah allowed Hayley to escape with her child and he daggered Klaus. To this act, Klaus retaliated by daggering Elijah with the Papa Tunde’s Blade and killed Elijah’s girlfriend Gia.
Their relationship again becomes strained early in the fifth season when Elijah’s memories are erased and the tragic death of Hayley which could have been prevented if only Elijah had his memories. But they reconcile again once Elijah regains his memories. Klaus sacrificed his life to end all of the Hollows magic and save her daughter Hope from the dark power of Hollow. Elijah’s love for his brother Klaus is evident from the fact that he decides to go together with his brother and sacrifice his life too.
