Spoilery thoughts on the last episode:
1) I dug it. It was a somewhat easy episode to write, though. Any sort of irrational behavior could be explained by people either being drunk, thinking they were saved, or knowledge that you're screwed and actually wanting to die.
2) Why do they always have crazy timing on things like this? It's not that easy to sprint down a bunch of hallways, up a bunch of stairs, take a bunch of hacks at a window with an axe and then detonate a grenade, run a block or so away and get to your car in like four minutes. Why not just add like five or ten minutes to the clock? It would have been the same exciting and narrow escape, just more believable. A minor quibble, but still kind of annoying.
3) Rick *knows* there's more out there than it appears because he saw something in the second episode. Maybe the other camp people don't believe him, but the doctor might. Wouldn't that possibly have changed the doctor's mind about wanting to die, or at least activated his sense of duty earlier? I don't know; maybe not. Interesting that he didn't play that card though.
4) I totally would have been cool dying in the blast. I mean, not so cool with being forced to die but if the explanation were given and a choice provided I would have died with the doctor.
