Hey! Hope you enjoy this! I'm gonna be honest and say that I'm struggling to update two stories every week. I'm thinking of updating one of the stories each week. Hope that's ok. Enjoy! I'm so confused as to why the formatting was weird cuz when it was weird on the other stories its cuz I copied it from word but this one I wrote in documents but i'll sort it for next time. Promise! Sorry!

The episode begins in Cicero, Indiana. A woman greets her daughter, who has been brought home by her ex-husband. The girl, Katie, claims that she hates it at her dad's house because there are monsters there.

'Monsters?' John questioned, frowning as he tried to work out what the monster could be.

Sam and Dean looked at other with confused face as they tried to figure out which hunt this was.

The dad is seen next working in his wood shop when the saw mysteriously turns on. He switches it off, and it comes back on and kills him.

'Is it a ghost?' John questioned.

'I'm not sure. I don't recognise this hunt yet.' Sam replied, looking confused.

Sam is in a diner, on the phone with Bobby, trying to crack a translation on the laptop in relation to Dean's deal. Dean enters and mentions the gruesome power saw death, then reveals that he really only wants to go to Cicero to hook up with Lisa Braeden, an ex-yoga instructor who gave him "the bendiest weekend of his life" over eight years ago.

'Oh. It's this one.' Dean said, with a hollow voice. He shifts uncomfortably in his seat. Mary frowned but decided not to ask after seeing the look on Dean's face. Sam's eyes also flicker towards Dean's in sympathy.

Dean dumps Sam off at the Cicero Pines Motel and drives to cookie-cutter suburbia, arriving at Lisa's house. She's surprised to see him, and he discovers that he's arrived on the day of her eight-year-old son's birthday party.

'Wait. You never told me this.' Sam said, looking at Dean with a distressed face.

'You have a son?' John questioned, feeling very unsure about suddenly being a grandfather.

'He's not my kid.' Dean replied.

Dean meets the boy and sees a striking resemblance, especially noticing his joy for his new AC/DC CD, the way he eats his sandwich, and the race-car birthday cake.

'Are you sure he's not you kid?' Jo asked, with a smirk.

Two women (one a local Realtor) ogle Dean; they both heard that Dean gave Lisa "the best night of her life."

Dean smirked, before looking down and looking away.

Dean goes over to talk to Ben, and finds he has an eye for the ladies. He gives Ben a long stare as the boy runs off to play with some "chicks," does the math in his head, and rushes off to talk to Lisa.

'So you at least thought that he might be your kid.' John commented.

'I swear I thought I was gonna have a heart attack.' Dean commented.

'Having kids isn't that bad.' Mary replied.

Lisa talks to Katie's mother, Annette Doolittle, who claims her daughter Katie isn't right. Dean shows up after she leaves to ask Lisa in a roundabout way if Ben is his. She denies the relation.

'Are you sure she's telling the truth?' Mary questioned, and Dean nods before rolling his eyes.

She then talks about the saw accident while they watch Katie and her mother behave strangely in the yard.

'That's odd.' John questioned.

Sam is in a diner when the mysterious woman who saved him in the last episode takes a seat across from him. She tells Sam she's interested in him, knows all about how he's got the "Antichrist" thing going for him and is the sole survivor of the psychic kids.

'Well that's not creepy at all.' Mary commented, frowning as she tried to figure out what was going on.

Sam is surprised to hear that she knows this and claims that his psychic abilities died with Yellow Eyes. She surprises him again by mentioning that something happened to his mother's friends.

'What?' John said, looking at Mary confused.

'I'm sure it will be explained soon.' Mary said, shifting in her seat.

She tells him to look into it and to call her when he's done, writing her phone number on the palm of his hand. Just before she leaves, she says there's a job in town, and then Dean calls to reveal that same fact: there have been four other accidents in that neighbourhood that never made the paper.

'Well, that's definitely not a coincidence.' Bobby commented.

Annette wakes up to find her daughter staring eerily at her, and then sees the girl's mottled and gray skin in her reflection in the mirror. Sam, disguised as an insurance agent, visits the wife of an accident victim and examines the scene where her husband fell off the ladder. He notices a red spot outside the window, a little girl giving him an eerie glare through the window, and a mark on the back of the woman's neck.

'That's so creepy.' Jo commented.

Back at the other house, Annette goes into the bathroom very rattled by her daughter's behaviour and freaks out when the girl tries to force her way in through the locked door.

'Oh, right. Is it a changeling?' John realised, and Dean nodded.

Dean sees Ben at the park looking sad because a bully has taken his video game. Dean encourages him to get it back by kicking the bigger boy in the groin, upsetting Lisa but earning him a huge hug from Ben in thanks.

'Not sure that's the best thing to teach a kid.' Mary said.

'He needs to be able to defend himself.' Dean protested.

Dean notices a set of creepy children staring him down as Lisa and Ben leave. Annette straps Katie into the car, and again sees her distorted face in the mirror. Instead of taking her for ice cream, she drives up to the edge of a lake, gets out, and releases the brake, letting her car and daughter sink into the water. She gets home extremely upset, only to find her daughter soaking wet but alive and well, asking for ice cream.

'That is the creepiest thing I have ever seen.' Jo said, shuddering.

Dean meets Sam back at the motel room, where Sam reveals all his research about changeling lore. It seems a changeling has replaced the kids, killed the fathers, and is feeding on the mothers. They realise any kid is at risk, and Dean insists they go check out Ben.

'That's just adorable.' Bobby said, earning roll of the eyes from Dean.

They arrive at Lisa's house to find that Ben has indeed been taken and replaced by a changeling. Dean finds the same red spot that Sam did at the other house, but realizes it's not blood, but red sand.

'I love it when the bag guys leave clues.' Bobby commented, sarcastically.

They pull into a vacant house in the neighborhood with a pile of red sand in the front and go in equipped with makeshift flamethrowers. Dean goes in the basement and finds Ben, the other kids, and the local Realtor from the party, all in cages. The fake Realtor confronts Sam, who misses her with his flamethrower.

'How did you miss?' Dean commented.

"'I was under a lot of pressure.' Sam said, with a sigh.

In the meantime, changeling-Ben starts freaking out Lisa. Jo shuddered again. Dean frees the kids and gets them out through the basement window while Sam arrives with the warning that there's a mother changeling. The fake Realtor shows up and tosses Sam and Dean around for a bit while Lisa and Katie's mum freak out over their changeling children. Dean takes down the Realtor and Sam torches her, causing the Ben and Katie changelings go up in flames in front of their horrified parents.

'That can't have looked good to the police.' Mary said, looking at Sam and Dean worriedly.

'It was fine. The real kids got back home.' Sam replied.

The Impala pulls into Lisa's driveway and Ben gets out to greet a relieved Lisa. Dean goes inside and explains the changelings to her and why he never mentioned his job before. She confirms for Dean, once and for all, that Ben is not his son. Dean is very disappointed.

'He seems like a good kid. I'd be happy to call him my grandson.' John commented, and Mary agreed. Dean smiled.

Lisa tries to help by reminding him Ben wouldn't be alive if it wasn't for him, and she kisses him after Dean declares he'd be proud to be Ben's dad. Lisa invites him to stay, but Dean reluctantly leaves, declaring this isn't his life.

'I wish you didn't have to leave.' Mary said, wistfully.

'Me too.' Dean replied, quietly.

Sam, back at the motel room, finds out through a series of phone calls that his mother's friends and everyone who ever knew her have been "systematically wiped off the map one at a time."

Mary looks down, sadly.

He tells the mystery woman this, and demands to know who she is. She reveals she's a demon, and tells him that she doesn't know what happened to his mother and her friends, just that it was all about him. She claims she wants to help Sam figure it out, and if he lets her, she can help him save Dean.

'Please tell me you didn't listen to her.' Mary said, Sam and Dean looked at each other, worriedly.
