int. kitchen/living room -- night

The room is dimly lit and a pajama-clad SARAH (22) has sunken down into the sofa, watching a horror movie.

Just as the music crescendos, Sarah's sister Dee (18) suddenly leans down from behind the couch, and puts her face right next to Sarah's.  

Dee

What are we watching?

Sarah jumps, screaming.  Then, seeing it's Dee, catches her breath. 

Sarah

(hitting Dee with a pillow)

God!  Dee!

Dee laughs and leans in, engrossed with the movie, blindly reaching into Sarah's snack bowl.

Sarah (cont'd)

Did you clean the bathroom?

Dee

Is this the part where he guts her? 

Sarah eyes Dee. 

Dee (cont'd)

(noticing the glare)

Housesitting is supposed to be fun, killjoy.  (happily holding up a pretzel)  Have a pretzel.

Sarah is stoic.  Dee playfully pushes the pretzel to Sarah's mouth as Sarah clamps her lips closed and tries to push away.

Dee (CONT'D)

Eat it!  (struggling)  EAT IT!!!

The struggle ends in Sarah and Dee laughing and Dee getting smacked with a pillow again.

INT. BEDROOM -- DAWN

Sarah, still bound to the chair, groggily opens her eyes as the Intruder breathes heavily into her ear.  Sarah is exhausted, ready to give up.

INTRUDER

(singsong)

Time to make a choice, princess.

Sarah looks over to Dee, bound to another chair.

Sarah

(crying, to Intruder)

Why are you doing this?  You're gonna kill us both anyway.

The Intruder shakes his head.  He puts up a finger, smiling.

INTRUDER

Just one.

Sarah (CONT'D)

Why?

He leans down slowly, sickly, looking at Dee but whispering into Sarah's ear.

INTRUDER

That's what makes it fun.

Sarah closes her eyes, new tears falling.

Sarah

Dee?

Dee

(drymouthed, barely able to speak)

Yeah?

Sarah

I love you, babe.

At first confused, but then understanding, Dee cries.

Dee

(like a child)

No.

Sarah

(trying to smile)

You're the best person I know.

Dee struggles with the little energy she has left.

Sarah

(to Intruder)

Do it.

Dee

NO!!!
