This is a Trunks and Pan fic, only Pan was raised by saiyajins and Gohan remarried and has another daughter.
I've had one ask why Gohan left Videl to die alone, well he didn't. sorry to be so confusing on that part, she left him before Pan was born. She disappeared and died later, Gohan never new if the baby survived or if Videl had lived. I hope that makes it more clear.
Also someone has said that Vegeta has already been to SSJ4. I Know that but he had Bulma build him a machine to add power to him, so he skipped SSJ3 and went to 4. But without the machine he hasn't even reached level 3. my story takes place four years after GT so...I guess Vegeta should have made it to lvl 3 by then, gomen again for the confusion.
