I'm too obsessed with antimatter
A one-atom wide line of antimatter along his skin, down through his shoes, through the ground, and into Voldemort's brain, where you make a microgram lump. Still doesn't kill him, precisely, but it should at least make him mad
If I were Snape, I would use a gas. Something which becomes hazardous after a certain time. Or merely change the nitrogen/oxygen balance after a certain time.
There are two prophecies at work here that I don't understand, which even now have to be vital to the ending
I really don't get why Quirrel is doing this knowing the prophecy of the stars.
Also, the transfiguration Harry is doing is an obvious hint as to the antimatter weapon ending.
Assuming that the Mirror of Erised works the same, Bellatrix is the obvious wielder
Weather's looking good
Who is Sirius? Fudge!
Seriously? Same location again?
