FYI - You can't tell by the video, but Chan danced this battle with an injury to his neck. I think he had fallen or something, but the injury resulted in him not having full mobility in his neck and there was some doubt he would be able to battle. But he made it, although he was in pain. RE: the battle itself.....although I liked the YG trainees' dance, I thought SKZ's dance showed much more humor, hard hitting dancing and versatility. IMO, they won the battle.
