Question about Gus Fring's Death

Np dude, hope you check it out and have a good time, best show ever on television hands down.

Sorry, I thought you at least watched the episode.

For reasons I won't reveal as spoilers, Walt got on Gus's bad side. I mean "I'm gonna get you sucka bad side".

So Walt was desperate. He needed some way to get the jump on Gus before Gus got him, otherwise Walt would have to leave town, his family, etc. So he asked his partner, who had actually been closer to Gus in the recent events, and had accompanied Gus on some personal outings. His partner could not provide much help, other than someone that Gus visited. So Walt says "maybe I could use this friend against, him, but not sure how". But Jesse, Walt's partner, says "No, he's not a friend. He's like some disabled guy Gus goes to and taunts". So Walt goes, "Hmm, he's not a friend, he's an enemy".

So Walt is able to use Hector and Gus's mutual hate to his advantage. He offers Hector the chance at revenge, cause he knows that Hector hates Gus more than Hector hates Walt (Walt played a role in the death of a few of Hector's family members). The first step is to get Hector to go to the DEA to make it appear that he is about to rat on all of his former partners, something someone in Hector's and Gus's circles would never do, even to an enemy. Hector can't communicate verbally, so any communication is slow using an aide that points at letters, but Hector doesn't say anything to the DEA. He just has the aide point to the letters "FU$% YOU" and is sent back to his retirement home.

Gus can't have Hector continuing to reveal stuff to the authorities, and figures it's time to kill Gus, which Walt knows that Gus will do personally because he hates Hector. So Walt was able to get Gus in the same room with Hector, and all Hector has to do is ring his bell to set off a bomb Walt has rigged to his wheelchair and the rest is history.
