2x8 - Star Trek: Hidden Frontier

An Andorian crew member is the only casualty when a conduit accidentally ruptures on the Excelsior. Radiation causes brain damage that results in a permanent case of clinical depression. While Henglaar looks into medical avenues to help the crewman and Counselor Elbrey does her best to keep him motivated, Captain Knapp also gets involved, lest the depression become too much and he becomes a danger to himself, and others around him.
