Yes, but that was just the last episode. I think he was more stunned than anything. I can;t wait to see how he handles it coming up.
I am still not convinced he is really THAT hard anyways, not yet. He has been slowly transforming through the first two seasons (which is them main part I am fascinated with as a student of psychology). We see flashes of his hardening but he is still part wimpy high school science teacher.
I've never seen Mad Men but I see the same fate for Breaking bad as I do for Dexter. Dexter is clearly running out of story; how long can they carry it on and make it believable. I think the same goes for Breaking Bad. another season or two and it will be so unbelievable that it won't be worth watching anymore.
