We have already discovered that new people frequently mean increased stress rather than help. Did anybody suspect such a brief look from the detainees? Certainly, Tomas is untrustworthy and crazy. I can comprehend Rick is not being a devotee of a zombie being pushed into him. Does anybody buy season 1 Rick would have returned by the covering a machete into the man’s head?
There’s a chance he aligned himself with Tomas, however, he also could have simply needed to play a game of tag. If Rick feels departure is the sole option, throwing out Andrew to an ocean of walkers is a rather sadistic approach to killing someone. I am shocked he saves the other two prisoners, but I am confident they consider his caution about not leaving their cell block.
