ALBUS: We get a message to Dad, he’ll find a way to get back here. Even if he has to build a Time-Turner himself.
SCORPIUS: We send a memory — like a Pensieve — stand over him and send a message, hope he reaches for the memory at exactly the right moment. I mean, it’s unlikely, but . . . Stand over the baby — and just repeatedly shout HELP. HELP. HELP. I mean, it might traumatize the baby slightly.
ALBUS: Only slightly.
SCORPIUS: A bit of trauma now is nothing compared to what’s happening . . . and maybe when he then thinks — later — he might remember the faces of us as we — shouted —
ALBUS: Help.
SCORPIUS looks at ALBUS.
SCORPIUS: You’re right. It’s a terrible idea.
ALBUS: It’s one of your worst ideas ever.
SCORPIUS: Got it! We deliver it ourselves — we wait forty years — we deliver it —
ALBUS: Not a chance — once Delphi has set time the way she wants she’ll send armies to try and find us — kill us —
SCORPIUS: So we hide in a hole?
ALBUS: As pleasurable as it will be to hide in a hole with you for the next forty years . . . they’ll find us. And we’ll die and time will be stuck in the wrong position. No. We need something we can control, something we know he’ll get at exactly the right time. We need a —
SCORPIUS: There’s nothing. Still, if I had to choose a companion to be at the return of eternal darkness with, I’d choose you.
ALBUS: No offense, but I’d choose someone massive and really good at magic.
LILY exits the house with BABY HARRY in a pram, she carefully puts a blanket on him.
His blanket. She’s wrapping him in his blanket.
SCORPIUS: Well, it is a moderately cold day.
ALBUS: He always said — it’s the only thing he had from her. Look at the love with which she’s put it on him — I think he’d like to know about that — I wish I could tell him.
SCORPIUS: And I wish I could tell my dad — well, I’m not sure what. I think I’d like to tell him that I’m occasionally capable of more bravery than he might think I am.
ALBUS has a thought.
ALBUS: Scorpius — my dad still has that blanket.
SCORPIUS: That won’t work. If we write a message on it now, even really small, he’ll read it too soon. Time will be spoilt.
ALBUS: What do you know about love potions? What’s the ingredient they all contain?
SCORPIUS: Amongst other things, pearl dust.
ALBUS: Pearl dust is a relatively rare ingredient, isn’t it?
SCORPIUS: Mainly because it’s pretty expensive. What’s this about, Albus?
ALBUS: Dad and I had a fight on the day before I went to school.
SCORPIUS: This I am aware of. I believe it kind of got us into this mess.
ALBUS: I threw the blanket across the room. It collided with the love potion that Uncle Ron gave me as a joke.
SCORPIUS: He’s a funny guy.
ALBUS: The potion spilt and the blanket was covered in it and I happen to know for a fact Mum hasn’t let Dad touch that room since I left it.
SCORPIUS: So?
ALBUS: So it’s coming up to Hallows’ Eve in their time as well as ours — and he told me he always finds that blanket, he needs to be with it on Hallows’ Eve — it was the last thing his mum gave him — so he will look for it and when he finds it . . .
SCORPIUS: No. Still not getting you.
ALBUS: What reacts with pearl dust?
SCORPIUS: Well, it is said that if tincture of Demiguise and pearl dust meet . . . they burn.
ALBUS: And is tincture of (he’s unsure how to say the word) Demiguise visible to the naked eye?
SCORPIUS: No.
ALBUS: So if we were to get that blanket and write on it in tincture of Demiguise, then . . .
SCORPIUS (eureka): Nothing would react to it until it came into contact with the love potion. In your room. In the present. By Dumbledore, I love it.
ALBUS: We just need to work out where to find some . . . Demiguises.
SCORPIUS: You know, rumor has it Bathilda Bagshot never saw the point in witches and wizards locking their doors.
The door swings open.
Rumor was right. Time to steal some wands and get potioning.
ACT FOUR, SCENE SIX
HARRY AND GINNY POTTER’S HOUSE, ALBUS’S ROOM
HARRY is sitting on ALBUS’s bed. GINNY enters. She looks at him.
GINNY: Surprised to find you here.
HARRY: Don’t worry, I haven’t touched anything. Your shrine is preserved. (He winces.) Sorry. Bad choice of words.
GINNY says nothing, HARRY looks up at her.
You know I’ve had some pretty terrible Hallows’ Eves — but this is undoubtedly at least the — second worst.
GINNY: I was wrong — to blame you. I always accuse you of jumping to things and it was me who — Albus went missing and I assumed it was your fault. I’m sorry I did that.
HARRY: You don’t think this is my fault?
GINNY: Harry, he was kidnapped by a powerful Dark witch, how can that be your fault?
HARRY: I chased him away. I chased him to her.
GINNY: Can we not treat this as if the battle is already lost?
GINNY nods. HARRY starts to cry.
HARRY: I’m sorry, Gin . . .
