And that sets it in stone. Sin Cara (Hunico) will be feuding with Sin Cara (Mistico) and whoever performs best gets to stay with WWE, both in storyline and in reality. Hey, Triple H was right all along. It IS best when stories are rooted in reality.
On a side note, the direction the Sin Cara character has taken is definitely for the better. It's easy to see the potential here, no matter who is under the mask.
