The scene with today's quote picks up in the script with:
Stunned, hyperventilating, Victoria doesn't know what to do. She's about to reach down for the boy when
HE BURSTS UP FROM THE WATER, SCREAMING!
Terrified, Victoria slips and falls, SLAMMING her head against the tub. As she struggles,.DAVID climbs out of the tub and starts across the bathroom. But when he realizes Victoria's been hurt, he stops... and begins to GIGGLE, his expression weird and malevolent.VICTORIA (CONT'D)
David....?
And it's at that point that today's quote from David -
Page 22 - David: 'I hope you die!'
- comes up.
And the reason that it's David's quote that comes up in the slideshow and not Vicki's second questioning if it's David is because that bit from Vicki was dropped from the pilot.
Also, I'm not so sure that Vicki slips and hits her head in the pilot. She might. But at any rate David doesn't giggle before he tells Vicki that he hopes she dies.
