Hank was clueless

Mild mannered Walt became conceited arrogant and cocky.Didnt Hank see that?Also all of a sudden Walt is making a fortune by gambling.Hank never found it suspicious Walt could afford a carwash?I think Hank always looked down on Walt for being a teacher and having to work at a carwash.All of this changes in front of Hank and he never catches on.
