Damien is still inside the market because he couldn't go to the entrance because his enemies are there. Instead, he has been entering different stalls to hide and escape them. Right as he turned into the hallway, he saw one of them so he immediately went back to where he came from but then the man rained bullets at him so Damien tried to dodge them all but then another man came and shoot him too.
They didn't even care if other people get hit which frustrates Damien.
At first, he was able to dodge until he felt a strong impact on his arm that almost knocked his body down then he saw Falcon aiming his gun at him with a smirk plastered on his face.
That is simply too much for a sixteen-year-old boy to bear, but Demian was able to withstand the excruciating pain and stood up on his feet to flee. When he looked at his arm, he noticed that the blood was gradually staining his white jacket.
"That fxckin' hurts," he mumbled.
