I'm looking for the following fics:
1. This one is pre-series and starts with John and Bobby in a bar. They hear a commotion in another part of the bar where Sam and Dean are (Dean is playing pool and Sam is watching) and see that some guy has punched Dean. Sam is pissed cuz Dean did nothing to provoke the guy. Someone else in the bar says the guy punched Dean cuz he reminded him of the guy his wife left him for. Dean and the guy who punched him take the fight outside and Dean easily beats him. At first, he seems to graciously accept his defeat and reaches a hand up for Dean to pull him up off the ground. But as he does so, the guy stabs Dean in the stomach. An ambulance comes while the guy is held back by other people from the bar.

2. The second fic is wincest. Dean and Sam had sex, but Sam reveals that he doesn't actually feel that way about Dean and he only had sex with him cuz he wanted to do something for Dean. Sam sees no problem with it and wants to continue doing it, but Dean is appalled and refuses. Later, Dean flirts with a witness and Sam gets jealous and realizes he does feel that way about Dean.
