Line?

[bluesox4113]

I've seen the movie a number of times (ahem, mumble.  Six.)  And 
there's one line I can't catch and it's driving me crazy.  It's in the 
scene in the Gryffindor room when Harry, Ron and Hermione are talking 
in front of the fireplace. Ron asks something to the effect, you don't 
think he [Voldemort] would try to kill Harry.  Harry says something I 
can't catch and then Ron says "To think I've been worried about my 
Potions exam."

What is Daniel's line in that scene?

Cheers,
Peg
