Zero ran to his destination after being told of his quest. He had to deliver a letter to a celebrity that is coming to town, and to do that he had to get backstage in order to deliver it. He soon arrived at the destination, a big concert dome. A show had just commenced, and as such everyone was packing up and going home, while the people who worked there were cleaning and reading for the next show the following day. Zero looked at the letter in his hands, the celeb would be backstage at this time, and he had to find his way back there, but at the present moment security was blocking the way to backstage. Zero spotted an area that was secluded and out of the way, and he immediately could tell that was the sign in area for volunteers. He placed the letter in his jacket and walked over to the sign in, signed in as "John Smith" and grabbed a badge and shirt and walked back into the stadium, at this point it was trivial for him to get backstage, as security just let him walk through. He then found his way backstage, and slipped the letter under the door of the celebrity. He then hid around the corner as she discovered and read it.
He then found his way back to the giver of the mission after signing out, the man gave him his money after Zero told him his success.
