Stuff Only Potterheads Will Get

Nigel Wolpert

Okay, a few chapters back, I said that the boy who gave the signal that Harry was back (Lightning has struck) was Colin Creevey. 

I looked it up on Pottermore and found out that it was a boy named Nigel Wolpert. 

He was not in the books but may have been created to substitute for Colin and Dennis. He was also in Gryffindor and died in the Battle of Hogwarts. 

I'll add a link if you want to look at the page.
