Looking at Arthur's back, it only took a moment for all the memories to come flooding to Quinn. His confident voice, his long black hair, and the fact that he could use the shadow. It had been a long time, an incredibly long time, since he had seen him.
That of course, was when reality had somewhat hit Quinn. That had to be the case, because these were all of the dead that were related to Quinn. Not just the ones he killed with his own hands, but those that he still had a deep thought in his mind about.
In fact, it was only now that he was realising it, even though the crowds of people that had surrounded him, not all of them were attacking him. They just were unable to do anything to help.
