[ EU ] Write an incredibly dark finale for your favourite light-hearted TV show .

The Doctor sat at the command console dejectedly. He had come so far and here was the end. 
 
 He thought back to all the people he had touched, Mary, Sarah, Rose, poor Rose, Rory, Amy. So many people he had touched. And killed. They're all dead now. 
 
 He could n't decide whether he regretted his life or not. There had been good times but so many bad. He had once said'Every life is a pile of good things and bad things' and how right he was. 
 
 Everything was finished now. He had lived for so long that he had become a shadow of what he once was. Before he had patience and mercy but over the billions of years he had dwindled into this sham of what he was. A monster. The blood bringer. A FAILURE. 
 
 He thought he could fix it all! Save the time lords, save Clara, be happy! No! He failed on all counts. Oh the mistakes he made were terrible. 
 
 And now he was at the End. All the clocks had wound down. He was likely the only living thing left now. Except the TARDIS but even that was dying. Any moment now it would flicker out and leave him in dark maddening isolation. He could n't even get out - the doors were shut! 
 
 He had a plan though, the final plan. He had a friend called Wilf who gave him something long ago. A primitive way to go but damned effective. 
 
 No more regenerations now.
