HARRY/VOLDEMORT’s hair begins to sprout, he feels it, he attempts to cover it. He pulls his hood over his head.
HARRY/VOLDEMORT: Then I won’t attack him. You are right.
DELPHI: Father?
HARRY/VOLDEMORT shrinks down — he is now more HARRY than VOLDEMORT. He turns his back to DELPHI.
Father?
HARRY (trying desperately to still sound like Voldemort): Your plan is a good one. The fight is off. You have served me well, now come here into the light so I may examine you.
DELPHI sees a door slightly sway open and then be pulled shut. She frowns at it, thinking rapidly, her suspicion growing.
DELPHI: Father . . .
She tries to get a glimpse of his face again — there is almost a dance happening here.
You are not Lord Voldemort.
DELPHI unleashes a bolt from her hand. HARRY matches her.
Incendio!
HARRY: Incendio!
The bolts meet in a beautiful explosion in the middle of the room.
And with her other hand DELPHI sends bolts to both doors as they try to open them.
DELPHI: Potter. Colloportus!
HARRY looks at the doors, dismayed.
What? Thought your friends were going to join you, did you?
HERMIONE (from off): Harry . . . Harry . . .
GINNY (from off): She’s sealed the doors from your side.
HARRY: Fine. I’ll deal with you alone.
He moves to attack her again. But she is far stronger. HARRY’s wand ascends upwards towards her. He is disarmed. He is helpless.
How did you . . . ? What are you?
DELPHI: I’ve watched you for a long time, Harry Potter. I know you better than my father did.
HARRY: You think you’ve learnt my weaknesses?
DELPHI: I’ve studied to be worthy of him! Yes, even though he is the supreme wizard of all time, he will be proud of me. Expulso!
HARRY rolls away as the floor explodes behind him. He crawls frantically under a church pew, trying to work out how he can fight her.
Are you crawling away from me? Harry Potter. Hero of the wizarding world. Crawling away like a rat. Wingardium Leviosa!
The church pew ascends into the air.
The question is whether it’s worth my time to kill you — knowing that as soon as I stop my father your destruction will be assured. How to decide? Oh, I’m bored, I’ll kill you.
She sends the pew down hard upon him. It smashes as he rolls desperately away.
ALBUS emerges from a grate on the floor. Neither notice.
Avada —
ALBUS: Dad . . .
HARRY: Albus! No!
DELPHI: Two of you? Choices, choices. I think I’ll kill the boy first. Avada Kedavra!
She fires the Killing Curse at ALBUS — but HARRY throws him out of the way. The bolt smashes into the ground.
He fires a bolt back.
You think you’re stronger than me?
HARRY: No. I’m not.
They fire bolts mercilessly at each other as ALBUS rolls quickly away and slams a spell into one door and then another.
But we are.
ALBUS opens both doors with his wand.
ALBUS: Alohomora! Alohomora!
HARRY: I’ve never fought alone, you see. And I never will.
And HERMIONE, RON, GINNY, and DRACO emerge from the doors, and fire up their spells at DELPHI, who screams out in exasperation. This is titanic. But she can’t fight them all.
There are a series of bangs — and then, overwhelmed, DELPHI tumbles to the floor.
DELPHI: No . . . No . . .
HERMIONE: Brachiabindo!
She’s bound.
HARRY advances towards DELPHI. He doesn’t take his eyes off her. All the others stay back.
