Because both "Earth-2" (episode titles) and "Earth Two" (onscreen subtitles) have been used, but neither has been used in-narrative, there is no clear spelling. Do we have a style guide on how to handle this, or are we giving "Earth Two" precedence just because we need to give something precedence?
