Miles Upshur is a man with no special abilities, no combat training, and no weapons. He faces sights that would drive men insane, he's tossed through windows, he has several fingers cut off, and he's hounded by psychotic maniacs who would like nothing more than to tear him to pieces and eat him.
He makes it through the asylum and into the underground facility where the Morphogenic Engine is located, the machine that's caused all the chaos and suffering. Once there, he's tasked with shutting down the machine keeping alive Billy Hope, who the Walrider is using as a host. And despite being chased by him, a super-powered nano-machine being, Miles manages to shut down all three segments of the machine, surviving a nearly lethal beating in the process. And despite all the abuse he's been through, despite being barely able to stand, Miles gets up and limps out of that room. And when greeted by a group of soldiers, even being shot isn't enough to finish Miles off. It takes half a clip of ammunition to fully put him down.
Waylon not only manages to escape the havoc of the nonstop slaughter of the asylum, and Murkoff being out for his guts, but recovers the whistleblower email in the process — everything he wanted to do. Yes, Murkoff will not rest until he is dead or incarcerated, but thanks to him, they are notgoing to be able to avoid their karma.
In a way, Chris Walker getting eradicated by the Walrider. Seeing that relentless, frightening brute of a man completely helpless before you is a sight to see, although Miles is sympathetic. Not that it or the one below are anything but Gorn, so it's still probably a bit scary.
By the same token, Blaire also getting eradicated by the Walrider and screaming out of sheer horror the entire time. After suffering through the torment that he ultimately caused, both indirectly and personally, it's so damn satisfying to see him get a well-earned gruesome death. This time, Waylon is not sympathetic at all.
