Reacting slowly to Billy's voice, Tony's head rolled against his palm to peer at him out of the corner of his eye, wondering why the kid thought he needed to take care of him. Scrubbing at his eye with the heel of his hand, he stretched out of his defensive huddle, like that might prove he was just dandy and wasn't the one that needed to be cared for.
"Drink," he suggested with a jerk of his chin, touching a knuckle to the bottle. The kid would just be sick if he didn't have the water. Then he fell quiet again, twisting his fingers in his lap, then running them inquisitively over the edges of the battery, like he could make it into something else. The car rattled, and the air got heavier with every passing second, everyone's movements slowing to stillness to concentrate on their breathing.
"How did you even get here?" Tony eventually asked, a whisper to not disturb the air, looking to Billy like his answer held the key to life. How did any of them get in a place like this? It was difficult to imagine that the stories of their fellow travelers were anywhere near as strange, but Tony would bet just as gripping.
