It feels like losing Ben all over again, except this time it's Klaus. Luther's face is wet with tears, helplessness twisted so tight inside him that he thinks he might explode, or just fall apart.

"It's okay, Klaus," he says when he apologizes again. As much as he doesn't want Klaus to go, he can't stand seeing him in this kind of pain. Slowly, he fades away, finally going still and Luther feels a piece of himself go with him.

For so long it had been his job to keep all of them safe. He'd even gone as far as to lock up Vanya because he thought that was the only way he could do that. And yet, the hard, unforgiving reality is that he couldn't. Klaus's death hadn't even been intentional, but an accident that none of them could've seen coming.

He puts a hand on Allison's shoulder and looks over at Diego who is just staring at Klaus's unmoving form in with ashen disbelief. He looks for Five, but he's not there. He's going to have to find him, but for now all he can do is try to adjust to a world without Klaus in it.

Even just having his light extinguished seems to make the inside of the barn darker and colder without it.
