Castiel had asked Sam about using the internet the night before, figuring that since he didn't need to sleep, he could search for a case. About halfway through the night he was hit with a sudden curiosity that most people will get at some point on their internet adventures.
He went back to the google homepage and typed C-A-S-T-I-E-L in the search bar and hit enter.
He squinted his eyes at one of the top results. What was- fanfiction?
He clicked the link and was presented with an array of stories- all about him. How could anyone possibly know who he was, and why would they be sharing stories?
He looked through the titles, and one caught his eye. The Best Pie Dean Will Ever Have.
He clicked it and began reading. At first he thought it was a good idea. "Maybe I should ask Sam to help me bake a pie" He thought. But then he continued. As he was bringing the pie to Dean he- died? He kept reading until the end, then stared at the screen for a while. For some reason, he felt like this was more than a story- it felt oddly familiar. The only thing he could compare it to was trying to remember dreams back when he was human.
It was just a silly, overdramatic story that wasn't written too well. There is nothing to worry about.
Nevertheless, he didn't feel like baking a pie anymore. He still thought a pie would be a nice gesture though, so he considered buying one.
He wouldn't make the same mistake as the Castiel in the fanfiction, though. He wouldn't go anywhere alone.
When Sam woke up, Castiel closed the site by finding the small x in the corner like Sam showed him. He pushed his chair out and stood up.
"Hi, Cas." Sam said, brushing his fingers through his hair and picking up the electric kettle and filling it with water.
"Sam. You are aware that Dean is quite fond of pies."
"Yes. Why do you ask?"
"I want you to come with me to purchase a pie."
"Why not just pop in by yourself and get it, then?"
Castiel fidgeted as he tried to think of an excuse. "I wouldn't know which one he would like the most."
"He will like any pie you get for him, believe me."
Castiel didn't know what to say, so he just kept looking at Sam. He looked up and met his eyes. He put down the kettle.
"Fine, Cas, I'll go with you if you really want me to."
"Thank you." He went up to him and put a hand on his shoulder, and their surroundings changed. They were in the supermarket, the bakery aisle.
"You pick one." Castiel instructed.
Sam looked over the choices. Blueberry, apple, and strawberry rhubarb. No cherry, which was always Dean's first choice, but he knew his second favorite was apple. He picked up the pie and felt Castiel's hand on his shoulder again.
"No, Cas." He pulled out his wallet. "I have money. We don't have to steal everything."
They walked up to the counter and purchased the pie. Castiel led Sam to a spot where no one would notice two men disappearing and popped them both back to the bunker.
"Okay Cas, we got your pie. You all set?"
"Yes, I believe so. I will bring this pie to Dean and he will be very pleased." He started walking towards Dean's room but stopped as he thought back to the fanfiction. Bringing Dean the pie had been his demise.
"Actually, I think I will wait for him to wake." He sat down and drank tea with Sam.
Hours passed and Dean didn't show. Sam called for him to "get his lazy butt out of bed," but there was no answer.
Finally Sam said "I'll go get him." and stood up. Castiel hesitated before saying "I'll come with you." He didn't want Sam looking for Dean alone. That fanfiction really had him spooked.
Sam shrugged and they headed towards Dean's room, Castiel grabbing the pie in case Dean needed coaxing out of bed. Once they got to the door Sam knocked on it and yelled "Come on Dean, we have stuff to do!"
When nothing was heard as a reply, not even a groan or a snore, Sam got a little worried. "Come on Dean, let's go, we-" He stopped midsentence when he saw the red liquid coming out from under the door.
He slammed the door open and yelled his brother's name as loud as he could. There was his brother, laying on the floor in a puddle of blood with a knife through his heart. He and Castiel ran over to the body, the angel dropping the pie facedown in the blood as he rushed forward.
The air was a mix of yelled and whispered "Dean"s, each filled with anguish and disbelief. He was dead.
Castiel couldn't help but blame himself. If he hadn't been so selfish and afraid for himself, he would have went to find Dean way sooner and he would be alive right now. They left him alone and then they neglected to come wake him up, telling themselves he was just lazy and was fine. But he was dead for who knows how long.
One thing was for sure. Castiel had to find whoever did this and get revenge for Dean, because Dean would never eat a pie again.
