Help Walt? Seriously dude? I dunno what to think man, this is one of the single most unpredictable shows I've ever watched but I absolutely do not see Hank trying to help Walt at all. I see Hank biding his time and doing LOTS of research about Walt. I would think that he would pick apart every single piece of information he can find on his brother in law for the last say 15-18 months. He'll take all the knowledge he already has like the fugue state, the car wash, Skyler's behavior, the gambling etc. All of it. Then, honestly, I see Hank going to Jesse. When I sit and think about it I think Jesse might help Hank take him down maybe in an effort to save Walt's soul or something like that. Think about the past that Hank and Jesse already have. Hank beat the living dog **** out of Jesse and Jesse was determined to make his life a living hell after that and I actually forgot what stopped him but I can totally see Hank going to Jesse and saying something like "Jesse, first let me tell you I am not here in any official capacity. Everything I'm here to talk to you about is off the record and I will consider it confidential. But I need to talk to you. I need to talk to you about Walter White." DUN DUN DUUUUN!!!! Lmao for real though I can definitely see something very similar happening.
