One word, amnesia.

Wukong got into a meditate-state. And he doesn't have to be woke up. But a demon appeared! So..Pigsy shoves hot pepper in Wukong's mouth wich makes his golden eyes flew open wide.

Wukong: "Don't worry master, i'll take care of that demon for you!"

After the demon got beaten, he turns to you as he smiles widely and bows before you.

Wukong: "What you want me to do now, master?"

Tang and Pigsy: "MASTER?!"

he thinks you're his master?! Oh lord...
