There's an immediate, instant narrowing of Asch's focus on that last comment, something in his eyes but also the air around him that goes incredibly sharp and pointed.

"If any version of that bastard shows up," he says, voice dripping with venom, but he doesn't actually finish the thought quite the way he began it. "If I can't kill him, then I'll make him regret whatever person or force caused him to be born if he so much as looks at my family again."

There's half a breath, and then his posture shifts and the sharpness relaxes into something more amicable but probably not less deadly. "Assuming Jade doesn't before I get there. Do you think 'cryogenic freeze' counts as death to the train?" It's almost cheerfully thoughtful.
