Alias "princess twilight 2.0" and "ultimate twilight" (SPOILER WARNING)

princess twilight 2.0 (128) -> ultimate twilight (300)
 
There does not seem to be any appreciable difference between these two tags. princess twilight 2.0 seems to have been created to refer to a form Twilight appears in in a leaked episode, but is being applied fairly indiscriminately to any image where Twilight has a Luna- or Celestia-like bodytype. The two tags appear to be entirely synonymous in what they’re used for, and I don’t see much of a benefit in keeping them separate.
 
EDIT: Also, because princess twilight 2.0 implies leak and spoiler:s09e26, those tags keep getting added to images where they absolutely no business being.
