Little is known about Dr. Harlow's personality. As revealed in his hospital lobby dialogue, he has worked with the Animal Hospital for a long time and has seen many hires come and go. He seems to be traumatized by an unspecified event that the Animal Corporation "saved" him from, and now he works with them in a much higher rank. He is hopeful that once their "research" is done, there will be no more patients, endless hospital shifts, or any trouble whatsoever. Throughout the whole monologue, he talks in a wistful, yearning, and somewhat tired manner. The only things Dr. Harlow can be seen doing are sitting in the lobby while watching the player(s) do all the work, speaking with an Animal Corporation employee in a hazmat suit outside the hospital, going to the staff room, or coming to the reception office after the shift has ended.
Dr. Harlow is presumably a bit of a coward. During the first emergency, he doesn't lift a hand to help the player(s) take care of the huge mass of patients
Speaking style
Speaks in gentle fragments, full of pauses and trailing clauses; favors hopeful “once” statements. Often avoids direct blame, uses corporate euphemisms, and repeats key phrases like a practiced script.
