"There was nothing you could do," Luther says, his voice shaking because as much as he tells Allison he doesn't feel it in his bones. He should've stopped it. He should've taken out the Swede or gotten in the path of the bullet or something.

He's failed again. Another sibling dead because he wasn't good enough or fast enough. And now they all have to deal with a world darker without Klaus's chaotic presence. And Allison is falling apart in front of him and there's nothing he can do to put her back together again.

"It's not your fault." He'll repeat it over and over and over again until she believes it, because it was his.
