Harry and Voldemort are on either side of the stage facing each other.

VOLDEMORT: This is it, Harry Potter! Our final battle! Soon, we will match wands - the winner will taste sweet victory, while the loser will feel the cold embrace of death. Prepare yourself, Potter! This is the end! AVARDA KE -
HARRY: EXPELLIARMUS!
(VOLDEMORT'S wand drops)
VOLDEMORT: Seriously? You used expelliarmus? The disarming charm? You .. you do realise I'm going to kill you, right? That's a thing that you know? I'm going to pick up my wand, the wand I killed your parents with, and I'm going to kill you with it as well.
(Voldemort picks up wand)

HARRY: I did it for seven years! Hey - I wonder if this spell works on me.
(Turns wand towards himself)
HARRY: EXPELLIARMUS
(His wand flies away)
HARRY: huh .. should have thought that through. Who designed this spell?
VOLDEMORT: That's it, Harry - I have you now! (Picking up wand) This is the end, Harry Potter. I'm going to destroy you - using the most powerful spell in the universe.
HARRY: No .. please .. not ..
VOLDEMORT: ACCIO VENGEANCE!
