Not sure what of this I've posted already but here goes (spoiler tagged in case you really don't want to know lol)

Spoiler:
INT. CSI - HALLWAY - NIGHT

as Natalie, in uniform, with gloves, pushes a cleaning cart down the hall, the cardboard box resting on top of it. She walks down the hall, completely unnoticed by those around her. Natalie works at CSI

She wheels the cart down the hall to Grissom's office. Nods to JUDY TREMONT at the Reception Desk. Judy is on the phone and casually waves back as Natalie enters...

INT. CSI - GRISSOM'S OFFICE - CONTINUOUS

Natalie wheels her cart in, past her Miniatures, all lined up in their cases. She doesn't want to look at them, so she turns away...

And sees Grissom's OFFICE MINIATURE on a shelf. For a moment, she stares. Not sure what to make of it...then, she shakes it off. No one else could possibly see what she sees.

She closes the office door, then takes her vacuum off her cart, plugs it in, and just lets it run, LOUDLY, not bothering to actually move it around.

She moves back to her cart, opens the cardboard box, and stares at her latest creation. She removes it from the box, puts it on Grissom's desk...but before we get a good look --

EXT. SARA'S CONDO/PARKING STRUCTURE - NIGHT

Sara walks from her apartment to her covered parking spacee. She's wearing a plain T-shirt and pants, holding a purse, a wheelie suitcase, her keys, and a phone. She's clearly stressed; it's going to be a long drive to San Francisco.

She BLEEP, BLEEPS! her car, and as she loads her stuff into the backseat (next to some extra CSI gear and field kit) -- She hears a VOICE coming from a neighboring parking spot --

NATALIE
(offscreen)
Sara?

Sara stands up and turns around. Before she knows what HIT HER, she's down on the ground.

ANGLE ON - SARA

On the ground, dazed. Keys and phone next to her on the pavement. She looks up to see --

NATALIE, coming toward her, giving her one more BLAST with a TASER. This time, Sara's out for the count...

BRASS
...We can't waste time screwing around with this nutcase. Bleach is cheap. I'll bring in a gallon and drip it on her until she tells us where. No one's going to argue police brutality on that --

GRISSOM
Let me talk to her.

A beat...and then Brass nods. Grissom walks out.

INT. P.D. - INTERROGATION ROOM "A" - NIGHT

...and Grissom enters. Natalie barely looks at him as he sits down across from her.

GRISSOM
Natalie. I understand why those other people had to die. They used bleach...

This gets her attention. Now she looks at him.

GRISSOM
And Chloe. She stole your father. She had to die, too -

NATALIE
I don't want to talk about this --

GRISSOM
Sara didn't use bleach. And she didn't take anything away from you. I did. If you want to punish me for what happened to Ernie --

NATALIE
I didn't kill her.

GRISSOM
Where is she?

NATALIE
Do you love her?

GRISSOM
Yes.

NATALIE
Is she your special girl? Your best one?

GRISSOM
Yes. Tell me where she is. Please.

She leans in, making him lean into her. Then --

NATALIE
(a whisper)
No.

She slides her tongue inside her cheek, moving something around. She sticks out her tongue and before we can even see what the GLINT is, she's grabbed with her hand and is --

STABBING GRISSOM IN THE NECK with a small X-ACTO BLADE!

Grissom GASPS as he recoils, and BLOOD POURS out of a hideous GASH in his neck.

Brass rushes into the room, dives to help Grissom.

Brass puts his hand over Grissom's neck and SHOUTS to N.D. uniforms who come running in...

And in the confusion, Natalie darts out the other door...

INT. NATALIE'S APARTMENT - NIGHT

Natalie slams the door behind her. And turns on the light of her lovely girly space. Just like we saw in the TEASER, calmed by her own sacred space. She takes a few deep breaths...and starts to SING:

NATALIE
"Oh, sad was the day for the little bisque doll, For they cut all her stitches away, And looked for the seat of the terrible ache: "T'was a delicate task" they all say...

Then, GRISSOM'S VOICE should be heard on the EDGES of her awareness...only slightly breaking through before she pushes them away by SINGING louder...

Natalie hasn't moved from her previous spot. The whole episode was a psychotic break. The only thing fantasy and reality have in common is the song she continues to SING:

NATALIE
"For none of the surgeons had ever before, Peformed on a dolly's inside..."

Grissom is still across from her, very much alive, completely unharmed, beseeching her.

GRISSOM
Just tell me where she is. Tell me where she is...

But Natalie just continues to sing:

NATALIE
"They tried to restuff her but didn't know how, And this was her wail as she died..."

EXT. DESERT - NIGHT

Somewhere in the Nevada desert. Sara lies under the wrecked Mustang. Wind is blowing. Nasty, sandy dirt clings to her face and arms. Is she dead? Hard to tell.

NATALIE
(voicover)
"I've got a pain in my sawdust. That's what's the matter with me. Something is wrong with my little inside. I'm just as sick as can be."

Sara's eyes flutter open. She opens her mouth slightly and tries to swallow. Then, she tries to breathe. Her chest heaves slightly and the pain of breathing casues an involuntary reflex in her free hand. It TWITCHES. Just like the doll...
