I couldn't fly to the London to see Harry Potter and the Cursed Child play (availability of tickets is another issue). Also, there's no video recording available (so, I want to yell at J. K. Rowling who disrespected millions of fans across the globe). I just read its script book (special rehearsal edition). Also, I have never seen a professional stage play in my life, so my imagination isn't working regarding several things.
Well, flights could happen using rope, but what about time travel scene?
ALBUS takes the Time-Turner from SCORPIUS - he presses down upon it and the Time-Turner begins to vibrate, and then explodes into a storm of movement.
And with it the stage starts to transform. The two boys look at it.
And there is a giant whoosh of light. A smash of noise.
And time stops. And then it turns over, thinks a bit, and begins spooling backwards, slow at first...
And then it speeds up.
DELPHI unleashes a bolt from her hand.
And, sorting hat?
The SORTING HAT walks through the students who spring into their houses.
It becomes quickly apparent he's approaching ROSE, who is tense as she awaits her fate.
(Sorting Hat was played by a human who also played Hagrid; I just want to know how sorting procedure happened)
Can you please explain how these things exactly happened on stage in case you watched the play in real?
