Before we get to today's new scene, we need to wrap up Scene 188, starting with the end as scripted:

188    CONTD                                      CONTD   188        Suddenly, Alex ENTERS THE SHOT, diving into the pool.        HOLD as we see him swim to the bottom and grab the        inert Tracy.  He brings her to the surface as Claire        helps him pull her out of the pool.  Again and again,        he pumps at her back as Claire stands watching.  And        then finally, with one huge gasp, Tracy begins to        breathe.

End of scene - though that's not quite how things play in the film - for example, Alex doesn't dive into the pool so much as -

- jump, and he doesn't retrieve Tracy from the bottom of the pool because he actually grabs -

- her partially floating body - and once he's brought Tracy to the edge of the pool, several bits of unscripted dialogue come up, beginning with Alex telling Claire -

"Get her, baby."

- and while he's pumping Tracy back, barely audibly he says -

"Come on, honey."

- and then Claire, who's not simply standing and watching but kneeling right beside Tracy, crys -

"Tracy."

- and after water finally spills out of Tracy mouth without a huge gasp or otherwise, Claire leans down to embrace Tracy and once again she crys -

"Oh, Tracy."

- and she begins to sob. And that's how the scene actually ends.
