Board Thread:Speculation House/@comment-11188061-20131110130812

This is completely speculation with not one bit of definitive proof to support it. Everything stated here are circumstantial evidences.

First, I'm working on the assumption that the Transient Princess is Yang's friend, and that Transient Princess is Cinder.

Second, I'll like to point out the uncanny similarity between Cinder's apparent ability, and Yang's Semblance.

Obviously, Cinder controls a more advanced fire/explosive/shockwave power, but it is entirely possible that Yang is just holding back. From the Yellow Trailer, we know that her explosion can be as powerful as Cinder's - if not stronger (her one shockwave near the end exploded at a far larger radius, and that one punch sent Junior clean off the roof. That ain't normal.

The theory here, is that Cinder has the ability to copy or steal a person's Semblance and make it her own. Yang's Semblance was her favorite for some reason - either to spite Yang when she found out, or maybe it's a symbolism of love for her friend? I'm just guessing.
