When the gang is able to break away from the walker herd, they duck behind a bush as Rick outlines the new plan: there are too many walkers, too spread out, for the few weapons and flares in the armory to take care of. Rick lays out a plan to head out to the quarry and recover the vehicles there, come back…I guess he is thinking evacuation, at least temporarily. As Michonne watches out (and looks majorly badass while doing so), Rick tells them that they as many drivers as possible.
