Is it wrong that the first thing I watched out of the whole 4 seasons & film was the scene in 3.1 Orientacion where Alex steps in during Michael's fight and snaps that guy's neck? I think it says a lot about the fucked-up nature of this pairing that this scene is what counts as high romance :-)
I deeply love the growing respect and trust that they build into something approaching genuine friendship during S4, but damn, the antagonistic, still-on-opposite-sides relationship of S3 is so very, very hot.
Ah, my boys. My boys!
