Trunks thought to himself..."well, just to be safe, I better write the cordinates down". He went outside and showed Bulma that he had written down the cordinates." You're such a good son", said Bulma, who was obviously proud of Trunks. Just when Trunks was about to go into the time machine she said "Trunks press the yellow button in case you want to get back here, I thought you wouldn't write down the cordinates, but how silly of me to think that. You're different from your father so I forgot". He launched off and everything went as planned. Everything was like in the show. Cell came and Trunks died. But Trunks was revived with the Dragonballs luckily. 2 years later--- Bulma heard a loud boom! outside her laboratory. She glanced outside not sure if it was a enemy. She saw the TIME MACHINE! Could it be? she thought. She saw a purple haired guy with a sword come outside of the Time Machine. IT HAD TO BE!     TRUNKS!!! TRUNKS!!, she yelled at the top of her voice. "HI MOM!", Trunks yelled back. She was thrilled to see her son came back to her. He told her everything went exactly planned except one thing. She had a questioned look on her face. She then saw a person that was coming outside of the Time Machine. She squinted her eyes, the hair of the person looked exactly like Vegeta's. She wasn't sure if it was a friend or foe to her.                                   Go up to the person                                                                     Ask Trunks who that is
