Hank already has taken da money, the paid rehab remember. Also the fact that Hank is good police works in WW and Jessies favour. As Hank cares alot about how ppl judge him and look at em, imagine if it got out that the biggest drug dealer in the Southern US is his bro in law. He would be the laughin stock of the agency.
he has to catch Hank on his own, and then make a deal wit em to stop and then sumhow shift da blame on sum1 else to get the credit for the big bust. Hank sets up a huge bomb or sumthin fakes his death every1 mourns, jessie then is da witness for Hank to nab maybe da dudes who they sellin da precursor too. and gives info on da cartel as well.
jessie then gets witness protection, up sumwhere cold, tryin to live the straight and narrow wit a wife n kid, dat wld b like death to jessie, he wldnt be able to handle it. he thinks he wants that life, but he cnt handle it.
Skylar is then stuck workin in da car wash, every day barely mkin ends meet as walt took da money wit em, or used it up sumhow. she has no hank, n da other dude is a cripple, and her bro in law n sis look at her wit a scowl at every fam dinner cuz of hank. Remember at start of show it had hank workin in car wash wit all da steam and chemicals n hatin it, now dats skylar, dat would be scary n her hell.
Hank wld probably have to do early retirement, or be stuck behind a desk as sum1 in upper command knows or finds out its walt but doesnt want this all to be big noise as mks da whole agency look bad, much like the Wire at da end, lester n white boy had to retire, daniels had to stepped down quietly. Now hank is stuck at home wit his rocks, listenin 2 his wife all day. dats hell for em
