Mathias nodded in agreement when Zhang gestured to the Radiation Roost, and followed him in its direction. When Zhang stopped to finally introduce himself and offer a hand to shake, Mathias shook it vigorously, and said "Dr. Mathias Johnson. I used to work way up north at the Institute, huge science complex, with some of the most advanced technology known to man. I was head of their medical department for a good number of years, but things took a turn for the worse, and now I'm out here, helping people as best as I can with what I've got left. It's good to meet a new friendly face out here in the wasteland." He then continued to walk into the Radiation Roost with Zhang, glancing over the people inside. "Perhaps you'd allow me to purchase you a drink as a good-will gesture, Zhang?"
