When we first met Elijah Mikaelson on The Vampire Diaries, he was looking for a way to kill his brother, the infamous NiKlaus Mikaelson. And he came very close to doing just that. But at the last second, with the promise of a family reunion, Elijah decided to let his brother live.
Jump forward to The Originals, and we learn that this brotherhood has been filled with a lifelong pattern of betrayal, forgiveness, and more generally, family loyalty. But when Klaus killed Gia in front of Eiljah in season 2’s penultimate episode, it’s possible he finally took things one step too far.
“There’s got to be a point at which the writers have to acknowledge the compound interest of all of these offenses. They need to mean something. I think that that’s the place that we’re approaching,” Daniel Gillies said. “I honestly think that we’re getting to a point where it is unforgivable. I would like to see him not get past it. My girlfriend can’t quite literally go up in flames in front of me, and then [Elijah and Klaus] resume the relationship.”
That being said, Elijah doesn’t exactly have time to cut his brother out of his life right now. With Dahlia’s attack on the horizon, Elijah will be forced to work with Klaus one last time. “Gia was just sort of a casualty thrown under the bus in the name of Klaus’ smoke and mirrors, but I think in order to defeat Dahlia, he’s going to have to relinquish whatever feelings he has towards that treachery and just move forward, because Dahlia is certainly an enormous threat to them all.”
