[The amount of irony in her first words is stunning even as he stumbles backwards. It would be kind of ironic if Allison killed him, all things considered. He's also not sure why Dahlia bothered talking her out of it. Isn't that what he's heading for anyway? One way or another.
It's the hug that really throws him off guard. One minutes she's threatening him and the next minute she's wound her arms tightly around his torso and she's crying and he has no idea what to do. He's not even aware of the fact that tears are streaming down his own cheeks.
He was going to die to bring her back, to give her a second chance, to give all of them a second change. Because he thinks it's what needs to happen in order to reset the balance. To make things right that he screwed up, whether he was in control or not.
He never expected to actually be able to hug her. His chest feels tight -- too tight, like he can't breathe and he's holding his breath because he's trying not to cry and doesn't realize he already is.
Even as she speaks, he nods slightly, because he doesn't disagree with anything she's saying. He had abandoned them. He's always been a selfish douchebag, even if Lydia thinks otherwise. He simply watches her, shoulders slumped as she addresses him the same way as Dahlia had. The same way that Lydia and Scott had. It's the least of what he deserves.]
