Story to go with:
Spike watched as the boy headed to his utterly dull routine. Spike wasn’t interested in the routine, cooking for the pathetic humans who were worse than his own mum when she had turned, doing chores all day. Then getting yelled at for not doing them right, though the poor boy had done such an excellent job, the floors had been spotless. Still, there wasn’t much Spike could do about it. He watched the boy as he cooked and cleaned and did chores all day, Spike watched, drawn to the energy and power surrounding the boy. It wasn’t as if he were in love with the child or anything. That was absolutely ridiculous. No, when he had arrived in this world Harry, for that was the boys name, had been brought here to the Dursley’s at only six months old. Poor lil’ chap. Spike had taken it upon himself to make sure that this child wouldn’t get hurt. It was like having the lil’ bit back. He loved it. Sure, it was hard at first what with him being unable to touch anything, but once he got the hang of being a ghost he could choose when to go corporal or stay invisible. If the Dursley’s didn’t give enough to Harry, he would steal something from the kitchens. With him around, Harry wasn’t going to get into any trouble, Spike would make sure of it!
------------------------------
I know, the story isn't very good, but it'll do for now. I might expand on it later.
Anyway, this is posted as a challenge to you. Spike dies in "Chosen" but he comes back to London, where his old house lay. It just so happens that his house was replaced by non other than the home of the Durlsey's. Seeing the abuse Harry has gone through, Spike decides to step in.
The rest is up too you. Basically its just a story where Spike becomes Harry's ghostly dad. You may post fanfics or fan art. :)
