Sorry this is so late. Still travelling and things have been a bit crazy.
Sam wakes up in a motel room to "Heat of the Moment" by Asia, where he finds Dean already up and getting dressed.
'I hate that song.' Sam said, shivering. Dean laughed.
Dean goes through a long and irritating morning bathroom routine and they go to the local diner for breakfast.
'You are so annoying.' Sam commented.
'I'm not that bad.' Dean protested. Sam rolled his eyes.
Sam tells him about a man that disappeared at the Broward County Mystery Spot. Dean orders the Tuesday special, "Pig 'n a Poke with a side of bacon," and as the waitress delivers their coffee, she accidentally drops a bottle of hot sauce on the floor.
'So that's how you knew to pick it up everyday.' Dean realised.
As Sam and Dean walk down the city block discussing the Mystery Spot, they run across a barking golden retriever, a blonde woman whom Dean bumps into, and movers struggling to get a desk inside a building.
Sam shivered again.
'You have no idea how many times I had to relive this.' Sam commented. Everyone apart from Dean looked confused.
When night falls they break in to the tacky tourist trap after hours, but as they're wandering through the halls, the owner approaches them with a shotgun. The gun goes off by mistake, and the bullet hits Dean square in the chest. Sam frantically rushes over to Dean and tearfully holds him as he dies.
'What the hell?' Mary questioned, looking very concerned.
'It's fine. I died loads in this hunt.' Dean replied.
'How does that helpe feel better?' Mary answered.
Sam wakes up to Asia again and sees Dean just like he did the day before - teasing him by turning up the song, lip-syncing, and bobbing his head to the beat.
'This is so weird.' Jo commented, looking confused.
The same scene in the diner replays, befuddling Sam who catches the hot sauce from falling this time.
'I've never seen anything like that happen before.' John commented, furiously trying to work out what the creature was.
They run across the dog, the woman, and the movers again while Sam convinces Dean to check out the Mystery Spot now instead of later. Dean agrees, steps out onto the street, and flies through the air in spectacular fashion when a speeding car hits him. Sam rushes to his side and is again traumatised by holding his dead brother in his arms.
'You're right. It didn't look cool.' Dean agreed.
'So you don't remember any of this?' Bobby commented, and Dean shook his head.
Asia plays again. A rattled Sam watches Dean go through the same morning gargle. He tells Dean in the diner that he's stuck in a time loop like Groundhog Day and that Dean's going to die.
'I am never watching that movie again.' Sam commented.
Back on the sidewalk - dog, woman, movers - and just before Dean steps out in the street, Sam pulls him back, telling him the car hit him yesterday. They go to the Mystery Spot, posing as reporters, only to get an act from the owner while Sam gets very irritated. Dean concludes that as long as he doesn't die, that will break the time loop.
'I'm guessing that didn't work.' John commented.
'Nope' Sam replied.
As Sam agrees, Dean steps forward, and the desk from earlier ends up falling on him, crushing him.
'Definitely didn't work.' Dean replied.
Sam looks on in horror, and "Heat of the Moment" plays again. At the diner, Sam is very anxious, again telling Dean about his time loop problem. Dean promises he won't die and tries to break the cycle by ordering sausage instead of bacon, but proceeds to choke.
'I would've thought that would work.' Jo commented.
"Heat of the Moment." Dean takes a shower, and Sam hears Dean yell and a thud. "Heat of the Moment."
'Come on! Not cool.' Dean commented. Sam sighed.
They're eating tacos, and Dean asks if they taste funny. "Heat of the Moment."
'Tacos? Really?' Dean protested.
Dean is electrocuted by plugging in his razor. "Heat of the Moment."
'That's just lame.' Dean commented.
Sam and Dean go back to the Mystery Spot, duct tape the owner to a chair, and Sam tears the place apart with an axe.
'Damn. You went full on psycho.' Dean commented.
'No I didn't.' Sam protested.
Dean tries to get the axe away from Sam, they fight, blood spurts, and Sam cries for Dean. "Heat of the Moment."
'Dude. You killed me!' Dean said, with a smile.
'By accident.' Sam protested.
By this time, Sam is extremely agitated. In the diner, Dean orders the Tuesday special again, and Sam tells Doris the waitress to clock some hours in at the archery range because she's a terrible shot (implying Dean died this way).
'At least getting shot by an arrow is cooler than the previous ones.' Dean commented.
He tells Dean angrily this is the hundredth Tuesday.
'Oh my god.' Mary commented, looking at Sam with sympathy.
He proves his point by repeating what Dean says at the exact same time and talking about the other patrons in the diner, not to mention catching the hot sauce again.
'That's impressive.' Cas commented.
Again they see the dog, old man looking for his keys (which Sam took earlier), and a woman bumping into them. Dean chases after the woman and finds that she has flyers of the man they're looking for. He asks Sam why in one hundred Tuesdays he didn't find out that she's the man's daughter.
'To be fair I was a bit preoccupied.' Sam replied.
Sam chases after her to ask questions, while Dean goes to pet the dog. Growling and mauling ensue.
'Seriously? A dog?' Dean protested.
"Heat of the Moment." At the diner, Sam, while on his computer, discovers that their missing man debunks tourist traps. He's apparently a pompous ass, and Dean points out that it's "just desserts" that a man out to ruin Mystery Spots disappears in one.
'The trickster.' Bobby realised, and Dean nodded.
Sam notices a man who has been having pancakes every day ordering a different kind of syrup, which is the first change to happen. Asia plays and Sam wakes up with a look of both revelation and fury.
'At least now you know what is happening.' Cas commented.
In the diner, the pancake man leaves, and Sam goes after him. He corners him in the alley and holds a wooden stake to his neck, telling him he finally figured out why he's repeating Tuesdays and watching Dean die everyday. Dean stands off to the side confused by what is happening.
'To be fair, I didn't remember the previous days.' Dean protested.
Sam says that they've killed one of his kind before, and the man turns into the Trickster and tells Sam they didn't.
'I'd forgotten about him. He's the one who faked his death right?' John questioned, and Dean nodded.
The Trickster admits it's been fun killing Dean every day, but that this time, the joke's on Sam, so he'll finally get the point that he can't save his brother. Sam threatens to kill him, but the Trickster says the joke is off and takes them to Wednesday with a snap of his fingers.
'I can't believe that he actually did a nice thing.' Bobby commented.
Sam wakes to a different song, "Back in Time" by Huey Lewis and the News, and is elated to see Dean alive and that it's Wednesday. They pack up to leave, and Dean goes out to the car first where he's held up at gunpoint by one of the diner patrons.
'Come on! You two can't get a break.' Mary commented.
'You think that now.' Dean replied with a sigh.
Sam hears the gunshot and rushes outside to see Dean on the ground, shot in the chest and dead. He holds Dean in his arms and closes his eyes, dismayed when nothing changes, before starting to sob.
'How did you guys get out of this?' John questioned.
'It's a long story.' Sam replied. Dean frowned.
A very dark montage starts with Sam driving the Impala, a distant look on his face. He's shown hunting alone across the country, pulling off some big kills, while Bobby leaves him a set of messages asking him to call, mentioning that he hasn't heard from Sam in three months and is worried.
'You really went off the rails.' Dean said, looking worried.
Sam arrives at a motel and the weapons in the Impala are now all organised in foam casing (à la John Winchester). Without expression, Sam fixes his own gunshot wound inside the room, cutting off his shirt, picking out the bullet, and stitching himself up.
'How did you do that without flinching?' Dean said in wonder. Sam rolled his eyes.
He eats alone, cleans a gun while examining with a cold stare the set of pictures on the wall tracking the Trickster, and makes the bed in meticulous fashion after waking.
'You're such a neat freak.' Dean said, with a small smile.
He brushes his teeth and stares in the mirror at a reflection that is defeated and emotionally dead inside. Finally, a message from Bobby plays in the background, claiming that he has found the Trickster.
'I bet that got your attention.' Bobby commented.
Sam meets Bobby at the Mystery Spot, and Bobby tells him that in order to pull off the summoning ritual they will need a gallon of fresh blood, meaning they will have to bleed someone dry.
'There's no way you could do that.' Dean commented.
Sam coldly tells Bobby he'll go find some, and Bobby is appalled that Sam is willing to kill an innocent person.
'Well I was super wrong about that. Sam, Why the hell would you do that?' Dean commented.
'It wasn't Bobby.' Sam replied.
Bobby gets out a knife and tells Sam to kill him instead. Sam agrees, but from behind, he pulls out a wooden stake and stabs him through the heart, saying he's not Bobby. The Trickster emerges and tells Sam he is right.
'That makes so much more sense.' Dean commented.
Sam tearfully begs the Trickster to bring back Dean, but the Trickster says that Sam should let him go because Dean will always be his weakness, his enemies know it, and nothing good will come of their sacrifices for each other - only pain.
'I think we may actually have learnt that lesson now.' Dean commented, and They both smiled.
'Took your time about it.' Bobby replied, rolling his eyes.
Sam still begs, so the Trickster snaps his fingers. Sam wakes up in the motel room with "Back in Time" playing on the radio. Dean is there, and a shaken Sam gets up and gives Dean a huge hug.
'That makes so much more sense now. Why didn't you tell me?' Dean asked.
'Like you told me about that dream about the demon version of you?' Sam replied, and Dean sighed.
They leave together and Sam is somber, deeply affected by his experience. He sees the unmade bed and realises that life without Dean will still happen.
