Dr. Andrew Morrison is a post-apocalyptic scientist who hides in a dark basement and conducts off-the-wall experiments. Before the outbreak, Andrew worked for a chemical research institute. He's exceedingly eccentric, obsessed with research, borderline crazy, and definitely not a people person. He was often ostracized at the institute. "Screwy Drewy" was his nickname. When Project Lazarus was launched, however, Andrew was the number one scientist who opposed it.
