[HPFGU-Movie] Sirius growling

[Amanda Geist]

The McGee asked a question I'd been wondering:

> (BTW, why did Sirius growl at Harry?-- just before Harry got on the
> Knight Bus).

I had a thought. It may have been shock, on Sirius' part. They gave the line
to him later: "You do look astonishingly like James" or whatever the exact
words are. You've escaped from a high-security prison where you hung on to
your humanity because you can become an animal, and where you have no happy
thoughts to hang on to, and even if you go looking for Harry, to have him
suddenly in front of you looking *exactly* like James might provoke a
reaction. And a shocked or startled reaction from a dog would be, well, a
growl or a bark.

~Amanda, not believing she's defending anyone who dislikes Snape like Sirius
does.
