I don't need the help of a sentimental fool.

[Seriously. They met five minutes ago. No stranger offers help without expecting something in return, having a knife behind their back, or just being the kind of idiot Asch doesn't want to associate with anyway.]

And I don't spar. I train.

[Sparring is 'fun', for people who don't rely on it to survive. He's a soldier. He trains. And he keeps walking, without looking around.]
