Help/Bug with Quest - The Spirit and Body of Shen-zin Su

[OGvics]

Hey. I've been doing all the Quests in Pandaren just like it have told me. In this one - The Spirit and Body of Shen-zin Su. It says how I should bring Shu and Wugou to the temple, but they wont follow me. In every Youtube clip or guide they follow directly the person doing the quest. Then i searched on your website for all the quest's in Pandaren to do in order and realized i never made the Quest before - Not in the face! Where Shu is suppost to wake Wugou. But now it seems like i can't do it. What the hell am I suppost to do? Yes, I have logged off and quit the game. Not really feeling to start all over again on an new character... Maybe it's possible to just go back in time or something like that?
