Call me crazy, but Steve Gomez was one of the most underrated characters on the show. The dynamic with him and Hank was always cool. Plus, he had two of the best lines ever on the show:
1. When the cousin, who survived the hit on Hank, later died in the hospital, as the doctors were announcing his time of death, Walt and a bunch of the DEA guys were watching from outside the room, and Gomez said, "Burn in hell, you piece of shit." Absolutely flawless delivery.
2. Early in Season 5, Hank and Gomez brought Mike in for questioning, and at one point, Mike sarcastically asks them where their handcuffs are and if he is under arrest. Later on, when they talk about the 9 guys in jail (whom Mike was making sure got paid to keep quiet), Gomez said to Mike, "One of your guys is gonna roll on you, and then we'll definitely remember the handcuffs." I LOVE that line.
