Marco, Callum, Rose, and OPEN
Being ordered around was not new to Marco, but working with silver was and the idea made him want to growl his displeasure. Rose was good enough to keep her frustration to herself however, and Marco wasn't going to give in to his own. Not now, not under pressure when someone really was relying on them working and working quickly. He'd already been pulling latex gloves from his own bag and sliding them on just in time to catch the solution offered. A curt nod given.
"We've got this," he offered, more to help ease the wounded man, though Marco didn't fully believe that the man cared what they were saying. Shock could be a bitch. With his own tools and the saline solution Marco started to work on the wound as Rose had, only momentarily pausing to rip the man's shirt a bit more so he had a better area of bared area to work with. Silver nitrate. Jesus, he'd only seen that shit in movies. The research he'd done had basically said it was pointless to try making it into a bullet due to its corrosive nature and the chemical reaction with water and fire.
Once the wound was flushed enough for him to begin working, Marco used his fingers and forceps to begin removing more pieces of the shattered bullet. "That's the only way they could make it work, make it brittle and do as much damage as possible," Marco noted as he pulled out the first bit of thin bullet piece.
