Staying as still as possible to not give Loki the impression that he needed to make any sudden moves, Tony slowly twisted one hand, palm out to the girls to caution them to a safe distance. He might have been playing flippant but this was not something for them to fuck with. Was there a convenient hand signal for 'get in the car and floor it'?
In the glare of the relentless sun, grasshoppers singing ceaselessly in the tall grass across the road, Tony could scrutinize the wandering Asgardian while he squinted back at Tony in the glare. Luckily, Loki wasn't looking so hot, they may have had a good chance to gain some distance. Coulson must have put up a good fight. Jesus, Tony hoped he was...well, if Loki was limping his way across Illinois, Coulson probably wasn't okay, but maybe alive somewhere. Which was slightly better than Tony had expected that to go when Coulson, the pompous ass, proudly announced his capture.
"Are you sure?" Tony pressed, turning his head to look up and down the barren road, disappearing over a hazy horizon to his right, not another soul along it's great length, and into the forest at his left, where a curious zombie burped its way out of the underbrush and stumbled until it found its footing on the harder ground. Not a lot of options, then, for a hitchhiker. "She doesn't look sober enough to drive," he noted, the tension reaching his voice now that they had two problems to contend with. What else might be in that forest and drawn after the noise of the car and the sound of their voices?
