After Rewatching, it seems like Hank should've suspected Walt sooner
The Chemistry equipment was missing from Walt's high school lab.
He sees them stealing the barrel on camera and knows a p2p cook is something for the "experts."
Then he knew Walt "bought weed" from Jesse so he knows they know each other.
Then Walt goes missing at the same time as Jesse (with Tuco) and is found at almost the same time as Jesse.
Then Combo gets shot and Hank wonders how the purest meth ever is being slung by some low level dealer.
Then he found out Combo and Jesse knew each other and Hank should've realized Jesse or Combo aren't good enough chemists to make that.
Then Hank gets the fake phone call about Marie and he was beating Jesse senseless he was yelling, "You got my wife's name and number! Who you working with?"
As soon as Hank had time to think about that phone call, he should've put it all together. Any thoughts?
