I love all the videos. I've already spoiled myself so much though.
Anyways, I'm not sure if I'm the only one thinking this, but is it just me or does anyone else think that Mcgonagall's line when she said, "I've always wanted to use that spell," sound sort of inappropriate for that moment? I mean they're obviously awaiting a bloody battle and everything is quite serious with Voldemort's army approaching that I can't help but think that for one thing she wouldn't use humor, especially Mcgonagall. And secondly, she's an experienced witch, she shouldn't be trying out new spells by that age and get excited over it like a child.

I don't know. That's just my opinion. *hides*
