The little girl certainly heard the loud boom of the .50cal. Probably a hell of a lot better than the humans there. Y'know, on account of her rather cat-like senses. She was a cat demon, after all. Anyway, considering she'd never heard a gunshot before - she wasn't even completely sure what a gun was - she, well, had no clue what it was. She was going to ask her brother, but instead watched in horror as a hole appeared right through him.
So, he certainly wasn't expecting that. He was about to say something about... Something. Hm, he couldn't remember what he was going to say. Though, that could be something to do with the pain from the fucking gunshot wound that very nearly took his arm off. Literally, if it had been up and a little to the left, it would have blown his bloody arm off. And if it had been down and a little to the right, it would have killed him. Hey, he may have been a demon, but he could still die from a .50cal bullet direct to the heart. Thankfully that wasn't what happened. He stumbled as the impact threw him off balance, but regained his footing. As soon as he realised what had happened - it took a moment - he swore very loudly. "Fuck!" That dissolved into a string of expletives that end in Italian. "Fuck shit crap cazzo fucking merda cagna stronza puttana fighe." He regained his composure with a final muttered "Shit." as he held a hand to the wound, which was bleeding rather profusely. If he had been human, the shot would have definitely killed him. As it was, his energy was rather quickly dissipating. It probably didn't help that he still held on to his human disguise.
The girl was very scared. This was why umani couldn't be trusted. Interestingly, the color of the glowing runes was now a greyish-yellow color. "You've been hurt..." she said. Well, nearly shouted; a mix of anger, upset, and fear. The humans would have definitely been able to hear it, as the girl was forgetting about being hidden, and more focused on her brother. As such, she was slowly becoming visible. At first it was just her outline, but it was soon every bit of her. Cat ears and all. But she didn't notice, as she was too busy running up to her brother.
"Hey, don't worry about me, kitten," he said to his now visible sister, forcing a grin. "It's just a scratch." It clearly wasn't just a scratch, considering the blood leaving through the fingers of the hand over the wound. His eyes went yellow as he turned to look for the shooter. There, up there, with a fucking horse mask for a head. He was noticeably a lot paler already when he turned back to his sister. "Hey, Ivy, do you remember any of the runes Mum taught you?" he asked her, kind of forgetting about the other people there. He didn't need to tell her what ones he meant. And no, he didn't mean any ones that could harm the bastard who shot him. He simply meant one to heal him.
Ivy knew what her older brother meant. She nodded. "Uh huh. Mummy made me go over them before I came here." The nine year old grabbed a long-ish stick and pushed it into the mud, starting to draw the runes her brother need.
