Chloe journeys to Edge City to interview Dr. Arthur Walsh. He used to be a professor of genetics at Metropolis University, but now teaches high school biology. He initially expresses reluctance to talk about Earl Jenkins, but he does invite Chloe into his office. He tries to hide some envelopes with a strange green logo. When Chloe mentions meteor rocks, Dr. Walsh mumbles something about Dr. Steven Hamilton's results being replicated outside of the lab, and someone named Donovan. Chloe tries to encourage him to talk by mentioning all the people who have been killed and hurt by the meteor rocks. When the bell rings, he agrees to meet with Chloe again next week, and they can exchange notes. (thetvdb.com)
