[ Vash leans against Nai, glad beyond words that he's got family here and isn't alone, like the brother he left behind. Like Knives had been, when his stupid brother left him. ]

That's not much of a choice. [ That came out ruder than he meant, didn't it? He leans forward, looking past Nai to frown apologetically at Knives. ] Sorry, big brother. But your Vash sucks. He shouldn't've left you like that.

[ Oh, Nai doesn't know about that, does he? Vash leans back against Nai, arms folded with frustration. ]

Big brother Knives's stupid brother left him all alone to go wandering around in the desert, because he's a jerk.

[ He's going to hold this grudge against his older self forever, apparently. ]
