1. WHY THE BROTHERS DIED?
The finale episode of Originals concluded the long journey of Klaus and Elijah Mikaelson. The characters were first introduced on the Vampire Diaries, their popularity led to birth of the spin-off titled ‘The Originals’. Season 4 saw the arrival of an ancient evil spirit named the Hollow which proved to be too much for the Mikaelson family. Hollow almost consumed Hope, but the Mikaelsons undergo a ritual to absorb a part of the Hollow’s spirit. But the spirit proved to be too powerful. Hope ultimately absorbs the entire spirit again inside her. But the spirit grows powerful that she cannot control her, it starts exploiting her from the inside. Klaus couldn’t bear to see her beloved daughter suffer at the hands of the malignant spirit. Therefore he becomes the vessel for the spirit.
The magic of Hollow was so powerful that it started amplifying the darkest and evil impulses of the Original Hybrid, Klaus was left with no choice, but to end his existence. In the final moments of the final episode, Klaus is ready to use the White Oak stake on himself to end his life. At this moment, Elijah lets him know that he wishes to die by his side. But why did Elijah decide to end his existence?
According to the show creator Julie Plec, the reason behind Elijah’s decision came from the fact that he knows deep down that he played a part in the death of Hayley. He could never be able to live with that. Being able to stand by his brother’s side as they walk into the death together was the sacrifice he needed to make.
