For a show so well written...
and it is, there has always been a scene to me that felt way out of character, it's when Walt and Gus discuss their relationship in a hospital surrounded by cops. It's literally a WTF moment for me considering we're well aware of how cautious Gus is.
Yet in this moment, Walt stops him in an area surrounded by people, including several cops, and decides to discuss their meth empire with Gus making comments about how they both hide in plain sight. I get he's banking on people not being able to overhear them, but that just feels so careless to me.
