Well, first of all, Saul comes swooping in to interrupt the Hank/Jesse interrogation, but not before Hank tells Jesse that he knows Walt is Heisenberg and, noting that Walt really seems to have done a psychological number on Jesse, offers a deal if Jesse would roll over on Walt. Jesse declines but his wording is telling: “Not to you.” Old grudges die hard.
After hearing from Flynn that Marie wants him to come over for no reason, what, Walt hauls out the big guns and tells his son that the cancer is back. Subsequently, Walt and Skyler invite Hank and Marie to a sit-down dinner at the local tchotchke restaurant where they attempt to present a cease-fire option. Skyler doesn't say much, but her one contribution is to volunteer the information that Walt isn't even dealing drugs anymore not that he ever did, what, so what would prosecuting him even accomplish. They both try to make the case that it harms the children too much to proceed with this. Hank's not interested in letting up one bit, and Marie's one helpful suggestion is, if Walt seems to think that his impending cancer death is a reason not to push the investigation, maybe he ought to just kill himself and expedite the whole process.
Without having much success, Walt and Skyler excuse themselves, but they leave behind what at first seems like Walt's video confession but instead is video of Walt confessing that Hank is the drug lord and that he's been forcing Walt to work for him all this time. He lays out an elaborate and outrageously false claim against Hank, tying everything from the series up and hanging it around Hank's neck. This appears to be deterrent enough for Hank, at least for now, and especially once Marie admits that Walt and Skyler paid for his medical bills, meaning he's got dirty money in his finances too.
With Hank momentarily neutralized, Walt then moves on to Jesse. He drives out to the desert for a meet-up with Jesse and Saul, wherein he makes the case that maybe Jesse moving out of state, with a new name and identity, might be just what he needs. Jesse recognizes this for the transparent manipulation that this is and practically begs Walt to treat him like a person. Walt responds by hugging a broken-down Jesse, which is its own manipulation, really. But it seems to work, and Jesse appears to agree to the plan to get him out of town. Saul sets up the meeting with his guy, a guy so fastidious that Saul has to put his foot down about Jesse getting high for the meeting. But, just before Jesse's supposed to meet the guy, he realizes that Saul had Huell lift the baggie of dope from his pockets ... suspiciously like how Huell lifted the cigarettes from him before the Brock-poisoning incident. Jesse puts it all together in his head, then proceeds to storm back into Saul's office and beats the shit out of him for his role in what Walt did to Brock. He then takes Saul's gun and heads off to confront Walt. Saul calls Walt, who guns up, but Jesse's not headed for him. He's headed for the (empty) White home, which he begins to douse in gasoline.
