Fuck. Not having the element of surprise is apparently enough of a problem, and he's annoyed when the stunner skids out of reach, but -- that just means he has the upper hand, here. he's sure he can overpower him, just like this, and not to mention. He never goes anywhere entirely unarmed. Tarn shoves him back, heading straight for the stunner, smart, of course, but Wash just follows after him, intent on not letting him get too far, grabbing at his arm to drag him back against him, to try and pull him into a headlock against his chest.

He's not letting Tarn get away too easily.
