So going back to this whole episode format: Dale is unflappably stupid, and he's failed to garner support from any of the people who typically listen to him. A normal person would give up or do something extreme, but Dale has no balls so you can pretty much rule out him freeing Randall or something. I guess the ideal play here would be for Dale to jump in front of the bullet, die, and then Grimes/Shane/Daryl walk up and shoot Randall in the head anyways.
