You're seen walking around the same dark grey Void after your encounter with the Shadow of Ruby. You walk around, still trying to figure out why you're in this Void. Then... It happens again...

Another pair of black smoke emerges in front of you and takes the form of someone else. As it completes the form, it's now... Weiss. Weiss Schnee. The Shadow looks to you as well, but giving you a neutral look on its face.
