When his sleeve was touched, Alan reflexively pulled his arm back with a small gasp and a brief look of surprise on his face. But just as quickly as it changed, his demeanor relaxed again and he couldn't help but laugh at how foolish he must have looked, even if it was only for a brief moment. "My apologies. Actually, the current condition of my arms is not from a bite or any recent injury. It, ah...it goes back much farther than that." His head and his voice dropped ever so slightly. "And it is not a very pleasant topic on conversation." As soon as those words came out, old memories began to flood in. He absentmindedly started rubbing the arm he'd just pulled back. "Scars that don't heal. Pain that never really goes away. Sometimes, I can still feel the flames as if they were burning right in front of me at that very moment." He closed his eyes only for a few seconds, but in that brief time, an all-too-familiar scene from days long past started to play out in his mind. He could see the laboratory again. Co-workers, friends, family, even the woman he loved more than anything in the world. Oh, how they burned, smoldered and charred until all that was left were the hellish memories emblazoned into his memory. Realizing that there was still someone else in the room, he quickly regained his senses, opened his eyes and started speaking in his usual cadence once again. "Ah, sorry again, I certainly didn't mean to space out like that. The long and short of it is that these injuries are nothing new, and...well, honestly, I just prefer to keep treating them myself." With that, he started gathering up his gear and supplies, moving them into the other room as he was asked. "Amelia, was it? I've always had a lot of respect for the medical fields; I don't have the stomach to poke around in the human body like you do. That's part of the reason why I've always stuck with chemistry. In fact, I was doing pretty well as a professor a few towns over before...well, you know. Armageddon." When everything was moved, he sat down with a relieved sigh. "So, seeing as you're a nurse, have you got any weird or funny stories to share from your time treating people in the postapocalypse?"
