The doctor sat in his TARDIS soaking wet, he was thinking of all the things he had to do, all the lives that he had ruined, all the lives that had been lost & all the things he had done wrong. Unknown to anyone the doctor let out a sob & let the tears run down his face. He hadn't felt this bad since he had lost rose at the battle of canary wharf,
She had come back & he had lost her yet again, which just opened up old wounds.
Left with nothing to do, the doctor decided to do one thing he hardly ever did, he went to sleep.
His resting time didn't last long, just as he had thought he was about to go to sleep, several alarms rang, including the cloister bell.
He rushed out of bed & into the control room "what is it, hey. What's all this about?" he asked the TARDIS "Rose is in danger!" the doctor stopped breathing for a moment "how?" he asked, his voice had gone quiet "you left her there, in the parallel world, you thought she was safe, but you didn't realize that the very man you left her with, was an distillation of all that is dark inside you, don't you realize exactly who you've left her with?" the doctor stopped completely this time "No, nononono" he said so fast that it all ran together, he swallowed the lump that was forming in his throat "you know what will happen, don't you?" the doctor knew what might happen "two possibilities…I don't like either of them" he said "I have to go back for her" he said, running around the console desperately seeking the warp star "Doctor, it wont work, the walls are closed, you left her there knowing full well you couldn't go back" the doctor stopped & picked up a hammer, he was breaking down "don't you ever blame me for what happened, don't you ever say never ever, she came back to me & I'll go back for her" he said holding the hammer in a threatening manner "THAT is exactly what is about to be unleashed on Rose, the only way you can get back is either a void ship or a dimension cannon, may I remind you that we don't have either of those" the doctor shrugged "should be easy enough to build a dimension cannon, if the humans on the parallel world can do it, I can build it twice as fast".
The TARDIS sighed inwardly, there was no way she could change his mind, he was too stubborn "It'll take too long to build a dimension cannon, by the time you get there it'll be too late, anyway why do you need a dimension cannon when you have me, there's just one little gap left. We don't have a sun to burn up this time, but you have a warp star, we can take the power out of that, it should be enough to make the gap bigger" the doctor was shocked that the TARDIS was going to help him break through the walls of reality "so we draw power & force it open? Won't that collapse everything?" the TARDIS sighed inwardly, sometimes she saw things Donna's way, the doctor could be a dumbo "no we don't force it open, we gently use the power to pull it open just a little bit so you can get into roses dimension & then we use the rest of the power to make an energy barrier so that it holds the hole in place while you get rose & her family" The doctor remembered something at that moment "Jackie is going to slap me for the next week" He muttered, the TARDIS evidently heard him because she laughed a little, Remembering how much rose had made fun of him for many days after that little incident "Anyway…how long will the energy barrier last?" He asked her, the TARDIS seemed to think It over for a minute "for an hour, one hour & a half if we are lucky" she said "Right, there & back again in an hour" He said confirming what the TARDIS had just said.
The doctor ran around the console, pulled a few leavers & they were off.
