His name was Jack Krauser; he was a former soldier with the United States military. He tracked me down in South America to ask me to try to heal his arm, which was paralyzed due to damage he'd sustained in a fight against a bio-organic weapon; apparently he'd heard of me from an acquaintance of his, and he thought I could reverse the damage.

I did what I could, and stayed near him during his recovery to keep an eye on him. We ended up talking quite a bit during that time period; I don't think we were friends, as I don't remember feeling that sort of familiarity, but I liked him well enough, and he seemed eager to talk to me.
