There was the sound of coughing in the distance. It wasn't very far off and it attracted Pietro's attention. Enough so that when the beam came, he didn't notice fast enough. There was a stinging, burning pain as flesh on his shoulder melted. The heat was intense and caused Pietro to groan in pain.
Instinct taking over, Pietro moved. He moved ahead of the beam, watching closely for its source. He picked up the nearest blunt object, a vase, and tossed it in Vision's direction as he continued to avoid the beam.
Dom didn’t see it happen or he might have warned Pietro. He only saw the aftermath. To be honest, he had never seen Pietro hit except by other speedsters or when he meant to get hit.
“You okay?” he asked nearly out of breath as he entered the room.
His shirt was still pressed to his mouth but he released it, not seeing any trace of gas here. The ground shook for a moment and Dom’s eyes rolled into the back of his head as the wing he had just come from collapsed onto itself, destroying anymore hidden traps and any traces of the ones that had been found.
Dom talked soft and fast, knowing Pietro could hear. “Not back there. Can’t go back out that way. Gas.”
Dom wanted Pietro to get away. Pietro was faster than Dom, obviously, and could have the house searched in a matter of seconds. They needed to make sure Wanda was okay first, he already knew that, no questions asked. And he knew Pietro agreed.
Dom wanted Pietro to go ahead and Dom would try to hold Vision off, but that wasn’t something he could risk telling him. The question that really bothered Dom was what he could actually do. How he could protect Pietro long enough to let him search thoroughly. Vision was immaterial and Dom only had power over inorganic objects. He felt the weight of the rock in his back pocket. Later, he told….no, promised himself.
