User blog comment:Waters Knight/Weiss killed 'herself' in the White Trailer/@comment-98.109.162.219-20131213230836

So, the Knight is "Weiss", and she has to "beat" herself? Well, I think that confirms that the trailer can't be real life.

Unless, of course if the RWBYverse has that "fight your other self" thing that we see in Naruto and Bleach
