What was the song playing as Gus was walking through the parking lot to his doom?  It was a good song, and almost too obviously made an elegy out of Gus' walk, along with the shooting style.  There was no way Gus was leaving the place alive after that song.

D'oh, nevermind, I see somebody else pointed out already, he was Chloe's douchebag husband on 24.

Can somebody smart tell me who the actor is that played the uppity cartel chemist that kept insulting Jesse?  Very familiar face, but I can't place where, and I can't find guest star cast listing for this episode yet.  Thanks.
