Arlene Galway (portrayed by Beverly Washburn) was a minor character from Season 2 of Star Trek. Appearing in the episode "The Deadly Years", she was a junior lieutenant aboard the USS Enterprise under Captain Kirk.
In 2267, Galway was a member of the landing party sent to Gamma Hydra IV to respond to a distress call. While on the surface, Galway was affected by a radiation sickness that caused hyper-accelerated aging. Among her symptoms was hearing loss, which she had never experienced before. When she approached Doctor Leonard McCoy about it, he suggested hypersonic treatment.
Later, McCoy suggested she lay down and rest in her quarters, but Galway was hesitant, fearing how she would appear when she awoke again. Captain Kirk, understanding her feelings, "ordered" her back to work, much to her relief. While leaving sickbay, she looked at herself in the mirror with dismay. Though younger than the other members of the landing party, except Pavel Chekov, she was the first to die, something McCoy attributed to her metabolism.
