Draco, Cunning?

I wanted to respond to a previous post earlier, and didn't write the 
number down. Now of course I can't find it. Someone said that Draco 
isn't cunning. But I have this to offer:

Draco was injured by Buckbeak. We know that. A great deal of blood 
was lost. It was two weeks before he was back in Potions and he wore 
the sling for a lot longer. Harry thinks he was faking, and so do 
most of us. Either he wan't faking, or he tricked Pomfrey, Snape, 
McGonagall, Flitwick and Sprout. So either he was cunning enough to 
fool all of them, or he was injured that badly. I think it would be 
very hard to fool Pomfrey.

I could believe Snape let him get away with it, if (and only if) it 
provided an advantage to the Slytherin Quidditch team for him to be 
on the injured list. That's assuming Snape knew he was faking. I 
can't imagine why any of the others would put up with it.

So, which is it? Did he fool all of them? Or was he injured that 
badly?

Potioncat, not defending Draco, you understand.
