I felt bad for Hank through most of this episode -- this series constantly surprises me on how down-to-earth and emotional it can convey it's situations and characters. Sometimes I even identified with them - Cotton's last conversation with Peggy hit a bit close to something that happened with one of my grandparents.
And you can say what you want about Peggy, but she's a very caring person when considering this.
I had to re-think the cause of Cotton's death.. it seemed silly until I realized that's exactly how an older person would die, in a situation that could have been prevented had they have been younger and sharper.
A+
So far this season, like The Simpsons' and Family Guy's, have been very solid. I'm impressed, Fox.
