He stepped neatly out of the way as the second body fell, reloading the taser as he moved. By the time the man had spit out enough dirt to try getting up again, the weapon was pointed at him. Aliens who looked very human and spoke their language seemed unlikely, but not every Incident was going to be like Roswell. The man, whatever he was, was awfully lively for someone who'd just been hit by a car, not that Coulson was complaining.

"I think that's his line." Coulson replied, nodding at the man on the ground.

He backed off enough to kick a knife away from the darker man's limp hand, noting the sudden tension in the blonde - concern? - confusion and realization. More confusion.

"He's only knocked out and I'd rather not do it again. We're not here to fight." Coulson lowered his tazer again when the man didn't move, though he suspected that had less to do with trust and more with the unconscious brother. He seemed to be having trouble keeping his eyes open, let alone fighting. "I think you both need medical attention."

"Do not touch me or mine again again, mortal." He shot Barton a narrow glare before trying to sit up. He made it onto his arms unsteadily before falling back down again muttering something that sounded like a curse. "We have no quarrel... Leave."

He didn't try getting up again. It looked like he was down and out this time. Coulson turned his attention to Barton.

"Check him for weapons. We should have medics here soon." He set to work on the darker one, rolling him onto his side. "Are you alright, Barton?"
