Captain Christiannsen had a prejudice against having women on his ship - but in the case of Wren Mary Lou, his prejudice was misplaced.  Mary Lou, as well as being young, beautiful, and with a natural gift for what she called "having fun", was a girl of resource who could face reality. Resourceful when the Gangerwolf was torpedoed and its survivors mercilessly machine-gunned. Realistic when she and her companions faced a brutal ultimatum!
