I'm looking for Three types of fics. Please Complete Slash or Gen fics only.

1. Fics where detective/cop/FBI agent/etc digs into Dean's mind and try to figgure out Dean's criminal record. Be it AU, Crossover, OC, etc. I've read and enjoyed quite a few and is desperate for more of law enforcment trying to understand the Winchester boys.
Defect & Hell and Back (sequel) GEN Criminal Minds Crossover. I really liked how even though the CM crew know he's been charged with a bunch of crimes, he still charms them.
All The King's Horses & As You Are Now (sequel WIP) GEN Criminal Mind Crossover. I really liked this one too. Especially how even after all he's gone through, Dean's still Dean.
Take a Long Line Numb3rs x-over. LOVE this one! How at the end Numb3rs crew was left whirling at the trust Sam and Dean had.
Oneiroi and Hephaestus CM x-over Slash. This fic was okay, I prefer them more fleshed out.
This Bitter Earth  another really good CM-xover that was about a plantation haunting. It was really good but I can't remember the title or the link. --TY Miki_Moo for the link!!!
Eat It Twilight CM x-over. Vampire hunting. This was a bit difficult for me to read because it jumped around so much I was confused about when what happened. I've lost link to this one too.
Somewhere between Perception and Reality Numb3rs x-over. This one was quite interesting too.

2. Fics where there's some type of mentor for Dean. There was a MacGuyver fic where Mac helps Dean build a present for Sam. Also Conversations where a college professor helps him out and the conversations they have. There's this other fic where Dean's English teacher does volunteering at the hospital and when Dean was in the hospital b/c of a car accident, she came and read to him.

3. Fics where Sam and Dean run into Sam's college buddies who don't like/dismiss dean.
In Reverse Where Sam and Dean happen to be at same place as a few of Sam's friends. One of them really jealous of Dean. Also the place has a bit of a history for Dean too.

Please, provide a short summary when you post a link? I like to know what it is I'm getting into. The longer the fics the better! because I love deep detailed fics!! Or if you've got any Dean-centric fics.... ?
Thank you for the help!
