I cannot locate a specific story.  This one has Dean, John, Sam and Caleb in it.  I can remember that Sam thinks they are hunting tree spirits but John disagrees.  Sam equips Dean to fight them but Sam and Caleb get hurt.  It may have not been complete that is why I cannot find it.  Any help is appreciated.

I'm looking for a fanfic of the Brotherhood!AU I read many years ago. It was not written by Ridley herself or the other active brotherhood writers. It was very Dean-centric, I think he was around 16 or so? He and Caleb were fighting about something and Dean felt very misunderstood and lost the whole fic. He started doing dangerous stuff with some other hurting kid of a hunter. I remember something about him riding a motorcycle on a train track and in one of the last chapters they were about to enter an old unsafe cable car. In the end Caleb safed him and they made up. The fic had around 16 chapters or so and I think I read it on Fanfiction.net, but I can't find it anywhere. Thanks for helping! 

Found it, it's called "Looking for space"

Hey guys...any help is appreciated.  I have search everywhere for a story I read and need help finding it.  John gets possessed and hurts Sam permanently (shattering his ribcage).  This spirit keeps trying to hurt Sam.  It possesses Dean but he fights back.  Bobby, Caleb, Josh are all in the story.  Thanks in advance!

I have read a few stories in the Brotherhood 'verse by Ridley C. James on fanfiction.net and I'm looking for a master post or reading order for the verse. I asked in a comment on one of the stories, but no luck.

ETA: Found - link in comments. Thanks again!

1. Sam was hurt on a hunt and Dean sheparded him to Bobby's where Dean falls prey to the flu or some other virus which should make him cooped up in bed. However, both Dean and Sam end up trying to take care of each other while not feeling 100% themselves. I'm pretty sure it was told from Bobby's POV; I remember this is the first fic I read where I called them idjits!
2. Sick Dean fic where he has to go through the pain of a gallstone. Sam stays with him through the whole thing even though it takes several days (maybe closer to a week). FOUND
3. Sam feels as if he is a screw up and runs away from his dad and brother. He believes that his dad hates him because he isn't just like Dean and he goes to Pastor Jim's house (it could have been Bobby's) where he ends up in a bed for a day or so 'cuz he's sick. Josh, Caleb, and Bobby all come to Pastor Jim's where they plus Dean and Jim take care of Sam while he recovers and learns to trust in his dad again. (Caleb and Josh, maybe Bobby held up guns against John when he wanted to see his son because they thought Sam didn't want to see him and his entrance might cause Sam to freak out). This one was weechesters, I think (don't hold me to this) Sam was around the age of 12. FOUND

Thanks you guys for doing this and always being so helpful :) I'm pretty certain I found all of these on fanfiction but I'm not entirely sure.

First one found! But still looking for the second one....

2.) Sam gets kidnapped by vampires and the story (pretty sure I read it on fanfiction.net) was about his time there. There was this one female vampire that he somehow makes a "connection" to (but not in a sexual way ;)). Sam is a teenager...

Can anybody help me?
Thank you very much!
