Yeah. My second is an epidemiologist by necessity, if not actually by trade or formal training. I came in at the tail end of an engineered biomedical attack where he was stationed--some kind of wasting virus--and helped him clean up. Though, at least that one was cooked up in a lab so we had a vaccine ready and I could just punch the guy responsible until he gave it to me so we could make more. Building one from scratch was a pain.
