I can't decide!

Although it's not going to be on this fansite, I am writing a new story on Trent. Now I know that it has been a long time since I wrote any articles about the way I feel that things went behind the drama but now that season 5 is coming I have 2 ideas in my head. The title is"The life and times of Trent" and it is about what happend after they got home from the world tour. However, it's going to take me awhile to finish and I've got a perfect idea on how the aftermath show would've really went if they'd have added the aftermath show to it before they start with season 5. Should I start at the begining of my story or should I go to the aftermath show to it's conclusion? Let me know asap.
