SCORPIUS: "Nice. Consider me engorgimpressed."

ALBUS: "Cedric used a Bubble-Head Charm to swim through the lake. All we do is follow him in there and use Engorgement to turn him into something rather larger. We know the Time-Turner doesn't give us long, so we're going to be quick. Get to him and Engorgio his head and watch him float out of the lake -- away from the task -- away from the competition…"

SCORPIUS: "-- people they loved."

Engorgio.

And then suddenly a jet of water emerges from the sink -- and after it ascends a very wet MOANING MYRTLE.

SCORPIUS: "So let me get this right -- the plan is Engorgement…"

He fires a bolt from his wand across the room. The soap blows up to four times its size.

ALBUS: "The second task was the lake task. They had to retrieve something which was stolen from them, which turned out to be --"

SCORPIUS and ALBUS enter a bathroom. In the center of it is a large Victorian sink.

SCORPIUS fishes a soap out of the sink.

ALBUS: "Yes. Scorpius, that soap, if you may…"

SCORPIUS: "But -- you still haven't told me how we're going to actually get to the lake…"

MOANING MYRTLE swoops down onto SCORPIUS.

SCORPIUS: "Myrtle."

MOANING MYRTLE (she giggles): "It's been a while. Boys. In my bathroom. In my girls' bathroom. Well, that's not right… But then again, I always did have a soft spot for the Potters. And I was moderately partial to a Malfoy too. Now how can I help you pair?"

MOANING MYRTLE: "What did you call me? Do I moan? Am I moaning now? AM I? AM I?"

SCORPIUS: "Well…"

MOANING MYRTLE: "Whoa. That feels good. Never used to enjoy that. But when you get to my age, you take what you can…"

ALBUS: "You were there, Myrtle -- in the lake. They wrote about you. There must be a way out of these pipes."

SCORPIUS: "Of course -- you're a genius -- Moaning Myrtle…"

MOANING MYRTLE: "Exactly -- Myrtle. Myrtle Elizabeth Warren -- a pretty name -- my name -- no need for the moaning."

SCORPIUS: "No, I didn't mean…"

MOANING MYRTLE: "What's my name?"

ALBUS: "The second task. The lake task. In the Triwizard Tournament. Twenty-five years ago. Harry and Cedric."

MOANING MYRTLE: "I've been everywhere. But where specifically were you thinking?"

MOANING MYRTLE: "Such a shame the pretty one had to die. Not that your father is not pretty -- but Cedric Diggory -- you'd be amazed at how many girls I had to hear doing love incantations in this very bathroom… And the weeping after he was taken."

MOANING MYRTLE: "This very sink. This very sink empties directly into the lake. It breaks every bylaw but this school has always been antiquated. Dive in and you will be piped straight to it."

ALBUS: "We can travel in time. You're going to help us travel the pipes. We're going to save Cedric Diggory."

ALBUS: "And we've no time to lose."

MOANING MYRTLE: "I love secrets. I won't tell a soul. Cross my heart and hope to die. Or -- the equivalent. For ghosts. You know."

ALBUS pulls himself into the sink, dumping his cloak as he does. SCORPIUS copies.

ALBUS: "Help us, Myrtle, help us get into that same lake."

MOANING MYRTLE (grins): "Well, that sounds like fun."

ALBUS: "We need you to keep a secret."

MOANING MYRTLE: "You think I can help you travel in time?"

ALBUS nods at SCORPIUS, who reveals the Time-Turner.

ALBUS (grinning): "It's all going to be entirely okay. Are you ready?"

SCORPIUS: "No, Albus -- Albus --"

MOANING MYRTLE: "I do like brave boys."

The boys are gone.

MOANING MYRTLE is left alone onstage.

HARRY appears at a run, a deep frown on his face, behind him DRACO, GINNY, and PROFESSOR McGONAGALL.

ALBUS: "Some for me and some for you."

He looks up, he and MOANING MYRTLE are alone.

ALBUS hands SCORPIUS some green foliage in a bag.

SCORPIUS: "Gillyweed? We're using gillyweed? To breathe underwater?"

ALBUS takes the gillyweed and disappears down.

SCORPIUS: "Remember, this time we can't be caught out by the clock…"

He takes the gillyweed and disappears down.

ALBUS: "Just like my dad did. Now, are you ready?"

There is a giant whoosh of light and smash of noise. And time stops. And then it turns over, thinks a bit, and begins spooling backwards…

SCORPIUS (a little bit scared, a tiny bit brave): "Then I'm entirely ready. For whatever comes."

SCORPIUS: "Tell me this is all going to be okay."

ALBUS: "Five minutes, that's all we allow for -- before we get pulled back to the present."

MOANING MYRTLE: "Oops, you caught me. And I was trying so hard to hide. Hello, Harry. Hello, Draco. Have you been bad boys again?"

PROFESSOR McGONAGALL: "But Cedric Diggory died years ago…"

MOANING MYRTLE: "He's using a rather pretty trinket thingy."

PROFESSOR McGONAGALL (consulting the map): "He's disappeared. No, he's traveling under Hogwarts grounds, no, he's disappeared…"

MOANING MYRTLE: "He's after saving a dishy boy. A certain Cedric Diggory."

HARRY: "Myrtle!"

HARRY: "My son is in danger. I need your help. What are they doing, Myrtle?"

HARRY immediately realizes what's happened, and is horrified.

MOANING MYRTLE: "He seemed quite confident he could get around that fact. He's very confident, Harry, just like you."

They find the boys' cloaks on the ground.

HARRY: "Albus… Albus…"

GINNY: "He's gone."

MOANING MYRTLE: "I think it was a secret, but I could never keep anything from you, Harry. How is it you've grown handsomer and handsomer as you've aged? And you're taller."

DRACO: "How is he doing this?"

HARRY: "What trinket is he using?"

HARRY: "He heard me talking -- to Amos Diggory… could he have… the Ministry's Time-Turner. No, that's impossible."

PROFESSOR McGONAGALL: "The Ministry has a Time-Turner? I thought they were destroyed?"

MOANING MYRTLE: "Isn't everyone so naughty?"

HARRY: "Albus and Scorpius are not disappearing and reappearing -- they're traveling. Traveling in time."

DRACO: "Can someone please explain what's going on?"
