Everything says he shouldn't let Nate walk away. Why would Nate come back? For him?But he can't force someone to stay with him, and so Anders nods.

"All right." Anders can't look up, can only stare at Purrelden as she bats at his robe tie trying to become the focus of attention again. His voice is as limp as the tie. "When you're back."

He's messed it up. Again. And he's going to be alone. Again. And it's probably better this way, because he can't see the rituals succeeding and Nate hadn't wanted to deal with Justice in the first place - a thought he can't pin down as Justice's alone or both, and he's too tired to try.
