There's a loud cheer.

LUDO BAGMAN: "If you're from Hogwarts. Give me a cheer."

LUDO BAGMAN: "AND IF YOU'RE FROM BEAUXBATONS GIVE ME A CHEER."

LUDO BAGMAN: "The French, finally showing us what they're capable of there. Ladies and gentlemen, I give you -- the final of the Triwizard tasks. A maze of mysteries, a disease of uncontrollable darkness, for this maze -- it lives. It lives."

There's a loud cheer.

There's a fulsome cheer.

LUDO BAGMAN: "And why risk this living nightmare? Because inside this maze is a Cup -- and not just any Cup -- yes, the Triwizard trophy stands within this vegetation."

LUDO BAGMAN: "If you're from Durmstrang -- give me a cheer."

LUDO BAGMAN: "Ladies and gentlemen -- boys and girls -- I give you -- the greatest -- the fabulous -- the one -- and the only TRIWIZARD TOURNAMENT."

DELPHI and the boys are forced to move as a hedge closes upon them.

VIKTOR KRUM passes across the stage, moving through the maze.

There's a loud cheer. DELPHI turns left.

The maze is a spiral of hedges that don't stop moving. DELPHI walks determinedly through it. Behind her she drags ALBUS and SCORPIUS. Their arms bound, their legs reluctantly moving.

DELPHI: "You will keep up or face the consequences."

SCORPIUS: "You won't have to mourn me for long, she'll kill me and quickly kill you too."

SCORPIUS: "Albus, we need to do something."

LUDO BAGMAN: "The perils are plentiful, but the prizes are palpable. Who will fight their way through? Who will fall at the final hurdle? What heroes do we have within our midst? Only time will tell, ladies and gentlemen, only time will tell."

DELPHI: "Where is he? Where is Cedric?"

ALBUS: "I know, but what? She has snapped our wands, we're bound, and she's threatening to kill you."

They move through the maze, SCORPIUS and ALBUS being compelled by DELPHI. As she moves ahead, the boys have a chance to talk.

A hedge almost dissects ALBUS and SCORPIUS.

SCORPIUS: "The hedges want to kill us too? This gets better and better."

SCORPIUS: "It won't work."

ALBUS: "Are you?"

ALBUS (desperate): "The flaw in the Time-Turner, the five-minute rule. We do all we can to run down the clock."

SCORPIUS: "I'm ready to die if it'll stop Voldemort returning."

DELPHI: "The prophecy must be fulfilled. We will fulfill it."

SCORPIUS: "No. We won't."

ALBUS (astonished): "You're not -- even on a broom."

ALBUS: "Where did she go?"

LUDO BAGMAN: "Now let me remind you of the current standings! Tied in first place -- Mr. Cedric Diggory and Mr. Harry Potter. In second place -- Mr. Viktor Krum! And in third place -- sacre bleu, Miss Fleur Delacour."

Thinking you can escape me.

DELPHI rises up after them. She's flying, and without a broom.

She throws the boys to the ground.

DELPHI: "Brooms -- such unwieldy, unnecessary objects. Three minutes gone. We have two minutes left. And you will do what you're told."

DELPHI: "You poor creatures."

SCORPIUS: "Does it matter? Which way do you think?"

Suddenly, ALBUS and SCORPIUS emerge from behind a hedge, they're running.

DELPHI: "You think you can fight me?"

As another hedge changes direction, DELPHI pulls ALBUS and SCORPIUS in after her. They continue through this maze of despair.

SCORPIUS: "No. But we can defy you. If we lay down our lives to do so."

MYSTERIOUS VOICE: "Expelliarmus!"

Bang. DELPHI's wand is pulled away from her. SCORPIUS looks on in astonishment.

DELPHI: "You talk too much, child. Crucio!"

DELPHI: "You're mistaken, child, prophecies are the future."

SCORPIUS: "Prophecies can be broken."

And DELPHI is bound. SCORPIUS and ALBUS then turn as one and stare in astonishment at where the bolt came from: "a young, good-looking lad of seventeen or so, CEDRIC."

ALBUS looks at SCORPIUS, finally aware what he has to do. He nods.

ALBUS (full of strength): "Yes. We will. And we'll do so gladly knowing it's stopped you."

DELPHI: "We don't have time for this. Cru --"

SCORPIUS: "You wanted a test, Albus, this is it, and we're going to pass it."

ALBUS: "Scorpius!"

MYSTERIOUS VOICE: "Brachiabindo!"

SCORPIUS: "But if the prophecy is inevitable why are we here trying to influence it? Your actions contradict your thoughts -- you're dragging us through this maze because you believe this prophecy needs to be enabled -- and by that logic prophecies can also be broken -- prevented."

DELPHI rises up -- full of fury.

SCORPIUS is racked with pain.

DELPHI: "Then you will die."

ALBUS: "Cedric --"

CEDRIC: "Come no further."

ALBUS: "I'm afraid you have to finish the maze."

Behind them, DELPHI's body creeps into movement. She crawls along the ground.

SCORPIUS: "No. You just have to free us. That's the task."

ALBUS: "Your dad loves you very much."

CEDRIC: "Are you also a task? An obstacle? Speak. Do I have to defeat you too?"

SCORPIUS: "You saved us."

CEDRIC thinks, trying to work out whether it's a trap, and then waves his wand.

ALBUS: "Just thought you should know that."

ALBUS wheels around, astonished.

CEDRIC: "What?"

CEDRIC turns towards him.

ALBUS: "Cedric?"

There's a silence.

CEDRIC walks confidently away. ALBUS looks after him -- desperate to say something, unsure what to say.

CEDRIC: "Emancipare! Emancipare!"

SCORPIUS: "But you're…"

CEDRIC: "Cedric Diggory. I heard screaming, I had to come. Name yourselves, beasts. I can fight you."

CEDRIC: "And now I can go on? Finish the maze?"

CEDRIC: "Then I shall."

The boys look at CEDRIC -- they are heartbroken.

The boys are freed.

CEDRIC: "Okay. Um. Thank you."

SCORPIUS: "Albus."

ALBUS: "No. Wait…"

SCORPIUS: "Albus…"

SCORPIUS: "The Time-Turner is spinning… Look at what she's doing… She can't leave us behind."

ALBUS and SCORPIUS both scramble to grab part of the Time-Turner.

CEDRIC looks at ALBUS a moment more, and then walks on. DELPHI pulls out the Time-Turner from within her robes.

And time stops. And then it turns over, thinks a bit, and begins spooling backwards, slow at first…

And then it speeds up.

SCORPIUS: "We had to go with the Time-Turner, we had to try to stop her."

And there is a giant whoosh of light. A smash of noise.

DELPHI: "Stop me? How do you think you've stopped me? I am done with this. You may have destroyed my chances of using Cedric to darken the world but maybe you're right, Scorpius -- maybe prophecies can be prevented, maybe prophecies can be broken. What is undoubtedly true is: I'm done with trying to use you annoying, incompetent creatures for anything. No more wasting precious seconds on either of you. Time to try something new."

ALBUS: "What have we done?"

The boys try to chase her, but they've not the slightest chance. She flies, they run.

She crushes the Time-Turner. It explodes in a thousand pieces.

ALBUS: "We need to stop her, Scorpius."

SCORPIUS turns back and tries to pick up the Time-Turner pieces.

ALBUS: "The Time-Turner? It's destroyed?"

ALBUS: "Hogwarts looks the same."

SCORPIUS: "Utterly. We're stuck here. In time. Wherever in time we are. Whatever it is she's planning to do."

DELPHI ascends again into the air. She laughs in delight as she sets off hard away.

ALBUS: "No… No… You can't…"

SCORPIUS: "I know we do -- but how?"

SCORPIUS: "Yes. And we can't be seen here. Let's get out of here before we're spotted."
