Aww, yay Neville. Nicely written. ]

The way you portrayed Neville here was absolutely brilliant! I've always felt that he deserved more recognition. Even after the final battle I'm sure it was all about Harry but Neville was fighting in his own way. A lot of the time he was made fun of and brought down by other people. So he was always pushed to the back anyways. He really did become a hero though, just as much as Harry did. It's ironic really that Neville could have been the one the prophecy was talking about and he is one of the ones leash recognized. Excellent job!

aww. That was cute. I liked it. I do not think N resentful but it is a thought.

Harry has black hair. He is not a brunette. Black.

The first sentence seems a bit long and fragmented. I would turn it into two or three so it makes sense.

Apostrophes make possessives. Hogwarts should have no apostrophe, unless you are referring to something that belongs to Hogwarts... Making it Hogwarts's. Same with St. Mungos.

N calls him You Know Who . Not Voldemort.

But well done!
