''Rival'' is from Latin 'rivalis' which refers to a person who uses the same stream as another. So, from the Latin root, ''rivals'' are persons who share a stream. Bernardo is using it in a broader sense, to mean those who share the watch duty with him. | ''Rival'' is from Latin 'rivalis' which refers to a person who uses the same stream as another.
