Wash's gaze sharpens as the guy turns to him, and he's already raising a hand to stop him. "Don't-"

Which is about when Athena interrupts them. Thank God. He turns and heads towards his familiar as she meows again. He picks the laser rifle up and tucks it under one arm, taking a knee to scratch behind Athena's ears with his other hand. "Good job. Thanks."

Is he ignoring the other guy, at least for the moment? Yes, absolutely. As far as Wash is concerned, Athena is better company.
