-EPILOGUE-
Sanders was convicted, and went to prison for 21 years without bail, though this was later extended after other charges were brought forward and again after an escape attempt (which was very nearly successful).
All the McFly boys recovered, though Dougie still had nightmares that woke him every night for months. They did their first televised interview together four weeks after the trial day, and so many galaxy defenders turned up to see them that they couldn't get away from the studios for six hours. They didn't mind though, because it had been so long since they had seen each other, and Dougie wanted to go out and sign everything he could for them, which gave him bad hand cramp, and then by the fifth hour a blister on one of his fingers.
They wrote an album together and toured it that same summer, and it reached number one in the worldwide charts, with even more people interested in McFly because of what happened. Danny used to joke that it had all been staged to increase publicity and sales, but stopped when some journalists took him seriously.
Dougie got his tattoo re-done over the scars on the same day he got taken, but a year later. The skin was still slightly raised, but he said it was a good reminder of how close he had come to losing it all, and that it made him appreciate everything he had every time he felt them, which was often.
And as for Harry and Dougie? Well, Dougie realised that, because he got to see Harry like it was for the first time again, he did, after all, have a little bit of a crush. Tom found out eventually (as he always did) and made another bet with Danny about what would happen between them. That got Danny excited and he told Harry that he thought he might still have a shot, if he felt the same as he had done all those years ago. Which of course he did.
So Harry asked Dougie out, and he said yes, even though it scared him how his new life was turning out. The rules were that it was kept casual, and they should always be, first and foremost, friends more than lovers. They were good for each other, Tom and Danny agreed, even though it was strange to have a couple in the band. The public didn't know; they had enough to be dealing with without confirming any suspicions that arose. Did they last? Well... that would be telling... ;)
