'The innocent never run' is what I once told you Yang. You haven't run along with it, with what the camera shows, but instead you've stayed and fought for your case. After what Coco said about her seeing an illusion herself during her battle with them, it's entirely possible foul play is happening.
I've seen a lot of malicious attacks before. Every time the person who did the harm would stand their gloating or smiling at what they'd done. After you hit Mercury you were completely confused which doesn't make any sense except if you saw something we didn't. In the time I've known you Yang you would never hurt someone intentionally.
*Ruby rushes forward and wraps Yang in a hug*
I don't believe the sister who took care of me and dad when mom died, who rode her bike to the vets with Zwei in the basket when he cut his paw, who time after time has put me before her and has always been there for me since day one, would ever do something like that unless there was a reason too. We believe you Yang.
