Sam exits the library. He hands a library card back to a pretty student.

Dean licks an ice-cream with boyish enthusiasm. He gives Sam a look of approval. "Did you get her number?"

"Dude. We're meant to be working."

"All work and no play makes Sammy a very dull boy."

Dean has ice-cream on his upper lip. He looks adorable. "You got something, there."

"What? Oh." Dean swipes the back of his hand across his mouth. "You planning on sharing?"

"Valerie's daughter Natasha was killed ten years ago when, get this, the bus she was on lost control and crashed into the lake."

"Ouch. Let me guess, blonde?"

Sam nods.

"So she's dead. And she's pissed about it. Vengeful spirit?"

Sam frowns. He's not convinced. "I don't know Dean. If it is a vengeful spirit, why wait till now? Natasha died ten years ago." Sam pauses. "Could be something else."

"Like what?"

Sam swallows. "A zombie."

Dean shakes his head. "Freaking civilians. Why are they always trying to bring back the dead?"

"She's been dead long time Dean. It's not going to be Natasha that comes back."

"And then we have to clean up the mess. Did you get an address?"

"Yeah."

"Right. Well seeing as you've got a thing for mature women you can go watch the old lady." Dean grins.

"Great."

"I'm going to go find Natasha's grave and salt and burn the bones."

Sam frowns. "Slight problem with that. Natasha's body was never found."

VALERIE'S HOME -

Sam picks the lock while Dean watches the street.

Inside the walls are covered with religious relics. There are crosses and crucifixes and porcelain Mary's and bleeding Jesus' everywhere.

"I think I'm going to puke." Dean looks at Sam. "What? Come on, this doesn't make you feel a little bit queasy?"

NATASHA'S BEDROOM -

Styled for a teenage girl. It's as though she never died. Everything is left as it was. Yet there's no dust so somebody must be keeping it clean.

"Okay now this is creepy."

Dean searches the room. "Gotcha!" He pulls a lump of blonde hair from a brush.

"Dean?"

Dean turns. Sam pushes the closet door open.

Inside the closet is an altar.

A pentagram drawn on the floor. Black candles. The JOURNAL lies open.

There's a life size dummy wearing a blonde wig.

A photo of Natasha is pinned to its chest.

"Now that's just sick" says Dean.

"You think she's summoned Natasha back already?"

Dean grabs the book. "I say we go do a little summoning ourselves. Summon the bitch and send her back to hell."

Downstairs a key is turned in the lock. Sam and Dean exchange a look. She's home. Time to leave.

They descend the stairs slowly, quietly.

Valerie is in the sitting room, taking off her coat.

Then suddenly Edward Cain moves into frame. He pulls Valerie into his arms and kisses her passionately.

Sam and Dean sneak past as the couple suck face. "I hope they remember to put their teeth back in" Dean says with a chuckle.

Sam and Dean head for their car.

"The old guy's still got it."

"Yeah, with his best friend's wife."

"That explains the guilt complex. Thou shalt not covet."

MOTEL - NIGHT

A stone bowl sits on a makeshift altar. Candles. A pentagram drawn in white chalk.

Dean fills the bowl with the hair he got from Natasha's brush.

Sam throws in a photo of the dead girl.

Dean opens the journal.

He begins the summoning ritual.

BUS -

Edward Cain whistles an upbeat tune as he drives. The bus is empty. His shift is nearly over. In the distance he can see the lights of the town. The bridge is ahead.
He sips coffee from a flask. He smiles to himself. Thinking about Valerie and their future together.
Suddenly the engine cuts out. The bus rolls to a stop right in the middle of the bridge.

"What the"

He starts the engine. Nothing happens.

The coffee flask starts to shake.

MOTEL -

Dean reads in Latin. The lights flicker.

Natasha appears before them. She seems surprised to have been summoned.

Sam shakes salt into the bowl.

"Wait!" Natasha cries. "No!"

Sam stops. Natasha implores him with her eyes.

"Don't listen to her Sam!"

Sam holds a lighter over the bowl. He hesitates.

"Sam!"

Suddenly the bowl is swept off the altar and flung against the wall. Natasha vanishes.

BUS -

The whole bus is now shaking.

Cracks shoot out across the road.

The bridge splits in two.
