Exactly!
Given both Mike’s and Walter’s personalities, those last words were perfect. They were also comedic gold: Mike was my favorite Breaking Bad character, so I was sad to see him go, but I was glad he told that nervous nelly Walter to just shut up already. Mike understood. He already knew the score. No need for a long-winded speech from Walter.
I surprised myself when I actually laughed after hearing Mike say those words.
And I’m glad Walter found some decency in himself to honor Mike’s request.
They ended up silently watching the Rio Grande river flowing by them until Mike passed. Very poignant scene.
Mike deserved a better death. But he made the fatal mistake of underestimating Walter’s paranoia.
