Remus Lupin

Luna, I had no idea you were worrying about whether you'd be allowed to come back to Hogwarts.

They managed with me, for seven years. I was a Prefect, in fact. That's why the Shrieking Shack was built; it's where I went during my transformations. It was, admittedly, a secret. But I was also an ordinary 11-year-old, a good student but entirely ordinary aside from being a werewolf. You're a heroine, a long-time member of the Order, someone who was bitten during the May Battle.

If anyone TRIED to keep you out -- if it were even a possibility, that they'd keep you out -- I would personally burn this school to the GROUND.

This is your school. You got your bite DEFENDING this school.

You have just as much -- you have a BETTER right than anyone to be here.
