Bill smiled as he nodded, Klaus always had something going. Trouble usually, but not the bad kind. Bill had always been a good boy, he excelled in school, he was organised and not just gifted but ready to put in the work to learn new things. But he had a habit of getting himself into trouble when it came to a pretty face. Which was maybe why in his room was a giant bag of drugs and the owner of those drugs was starting to realize he had Bill wrapped around his little finger. Even if Bill was flexible enough to get wrapped around a couple of others as well.
He was surprised that Klaus continued on, thanking him when there was nothing to thank him for. Bill pulled back enough to look at him, dragging his fingers slowly through his short hair. "You think I'd leave without you?" Bill said with a little smile and it wasn't really a question.
Bill hesitated for a moment as he looked down at him. "Back home? When I was a kid, there was a war, my parents and their friends fought on the right side. A lot of good people died or worse," he explained quietly. "Just before I ended up here, things were starting again, people were dying again. I know what it looks like, when you've seen too much. Been through too much," Bill said.
