Guilian nodded, understanding that he had a battle on his hands, but he was pleased to know that it would get easier each time.
Mindless killing machine. The words were just as distasteful to him as they were to Rabastan, but he now knew how easy it was to just cross the line and so easily be that.
Turning back to the Muggle, he knew his last breath wasn't far away, but he wouldn't be taking it away himself. He nodded at the order to rest - magically and physically. He would have no trouble now with either, and the comfort of the Casino was almost as good as the comfort of his own home.
He realised now that he looked to Rabastan as some sort of mentor figure in this. A father figure. That's what he needed. He doubted his father would even approve of what had happened, let alone try to help him best come to terms with this part of his nature.
Clasping Rabastan's wrist in a firm shake, he conveyed his gratitude for what he had done. Merlin knew what would have happened had he let the darkness take over. "What if I need you - you know - if anything should go wrong?" He didn't want to admit to weakness, but if he was learning to control his addiction, he wanted to be prepared for anything.
