I don't get this "career suicide if people find out Hank's brother in law is Heisenberg" argument. Maybe it'll pan out that way, but for now he's actually the person who wanted to press forward with the investigation repeatedly. So he missed something that was "right under his nose." Big deal. What obvious signs did he miss, really? What could the higher-ups point to and say he should have known better, so this guy's finished moving up through the ranks here, even though he singlehandedly put a stop to an enormous international drug cartel, which is kind of a big deal for DEA?
If the writers decide to make the whole "career suicide" thing a factor that motivates the character, I'd be fine with it as long as they explain it a little more. But I'd be totally fine with it being a non-factor too.
I don't think they would have had Hank's old supervising agent have to resign/be demoted/be reassigned for his longtime relationship with Gus if we're not supposed to believe that Hank will have similar concerns about him and Walt.
Hank is working the case from home for a reason.
I agree that that's likely what we're supposed to think and how it'll play out.But I hope not. The situations are still fairly different. The other dude repeatedly brushed off evidence on Fring, and waited for nursing home and laundry explosions to consider it.
Hank would've been bringing in a book he found on the crapper and not enough evidence to even get the DEA to take it seriously (if not for an agent wanting to investigate his own brother in law).
I hope, by 9:15 on Sunday, Hank's got all his boxes spread at the DEA office with Gomie and the crew because that's not what we've been led to expect and it's so different from how every other show would handle it.
Not a criticism because it's probably the most interesting way to do. "What should I do, what should I do...oh #### it's too late to take the legal route now" thing is probably more dramatic than doing the smart thing.
