The first two questions run through my mind often too. Such as, was Kimmet the de facto leader of the U.S? Did he have authority over the mayor of Boulder?

As for Ink sleeping, Micheal did mention there being a bed in his secret lair, underground. But, I wondered what else did he do. Was he all work and no play? What did he eat? Did he know he was a zombie? Did it bother him? Did he have a zombie girlfriend?

Kelly was a lawyer, Angel was from a rich family and Burt didn't exactly have a stockpile of cheap weapons. I think what people did before the outbreak pretty much didn't matter afterwards unless they could use their talents.
