Hank knows who's it is, he commented on it when Walt came to cry crocodile tears at him.
Did someone say that there was some point in this episode where Walt seemed disturbed by what happened to the kid? Because I musta missed that.
The dinner scene was so great. First time Jesse's been funny in a long time. Also really great to see Jesse's conscience figure strongly into things in a way that isn't a total breakdown. He knows what he's in on is wrong.
Walt told Jesse he understood his feelings and hadn't slept in days since the kid was killed...Which even Jesse started to realize was a crock of shit when he saw Walt whistling while he worked.
That dinner scene was amazing.
