Gabriel appeared to walk back out of the exit, strolling quite casually through the scattered and horribly burnt corpses. Some guards still lingered, crying out in pain. He didn't seem to care and let them continue to suffer rather than wasting time putting them out of their misery. The residential portion of the estate was relatively untouched given where it was situated, that being directly being the main complex that housed the network hub and even served as a warehouse. Sure enough, standing in the center of a courtyard that must have played host to numerous events in the past was the Don himself. He seemed to be looking around, as if reminiscing of the former glory that his estate likely used to have.
When Gabriel approached, he turned to face him and then drew a gun. It was unsurprising that he wouldn't simply die without trying to kill his would-be assassin in the process. But he was just as fast, if not faster than Gabriel and this contest of who could draw and fire the fastest ended in a draw. With both participants striking a decisive blow to the right side of the of their respective torsos. Gabriel staggered backwards but kept a grip on his gun, while the Don lost grip of his own firearm and instead opted to charge his assailant. He was strong, immensely strong. They would trade numerous blows, with Gabriel seeming to suffer from them the most. It was likely that Zoe wanted to help, but they were too close together and it was likely that she'd kill Gabriel in the process. It was also perhaps some kind of cultural anomaly, where someone of the Don's status should only be killed by another pure native.
If Zoe wanted to help then she would need to land, and land she did. Close enough that she could rush towards the struggle quickly. She would arrive to see you Don wrenching Gabriel's pistol from him and lining up a shot at her, only to have Gabriel kick his hand aside and cause the shot to miss entirely. But in doing so he had made himself vulnerable, punished by being dragged into a struggle for the gun. The Don had the advantage, slowly but surely raising the pistol towards Gabriel's head, and there was very little to be done about it from the angle Zoe was at. Gabriel himself would not be able to twist the gun in any way that put the Don at risk, he was locked like this and being choked as well. He would have to let go, and that would mean certain death.
The situation was dire yet again. But by contrast Zoe could see that Gabriel was looking right at her, his eyes wrinkled with amusement like when he had smiled at her hours ago. In one deft motion, he dropped down, twisted himself and audibly dislocated his shoulders. But now his head was absent from the firing solution, the Don did not have this luxury. And soon enough, he had no head either.
At this point, Gabriel simply dropped his gun and slumped down to his knees. His head swayed as if he might pass out at any moment from the immense pain. But at least it was done.
