I'd forgotten that the Sorting Hat was originally Gryffindor's [it tells us itself, in the first sorting song..] I kind of like that the sword came back into the story and didn't just stay with Griphook. That would've been a bit of a disappointment considering how Griphook was kind of a little snob.Su: How did neville get the gryfindor sword, is there a link to the hat
J.K. Rowling: Yes, there is very definitely a link to the hat!
J.K. Rowling: Neville, most worthy Gryffindor, asked for help just as Harry did in the Chamber of secrets, and Gryffindor’s sword was transported into Gryffindor’s old hat
J.K. Rowling: – the Sorting Hat was Gryffindor’s initially, as you know.
J.K. Rowling: Griphook was wrong – Gryffindor did not ‘steal’ the sword, not unless you are a goblin fanatic and believe that all goblin-made objects really belong to the maker.
