Summary: Sam gets a new smart phone. There is also a gen version here (http://ohsam.livejournal.com/196018.html?thread=1428658#t1502898).

#1 could be Pretty Tiger (http://archiveofourown.org/works/549058) by Annehiggins (http://archiveofourown.org/users/Annehiggins/pseuds/Annehiggins/works?fandom_id=27)
Something is preying on young men, something that Dean has encountered before.

The exact line I'm thinking of from this story is: "It's always been about someone else, hasn't it, Dean?" he whispered into his brother's hair. "No one ever let it be about you. Especially you."

Yes! That's it, one of my favorites :)
Thank you so much for helping me :x
