The Walking Dead "18 Miles Out"

Markguns

So what about all the symbolism is throughout this episode.. Shane sees a lone Walker Twice... he is still alone, even though he is "Welcomed back" at the end.... The song at the end is "Drivers Seat", Rick is in charge.... Knives Knives Knives, symbolism; The scarcity of supplies and challenges ahead. The cruel reality of all the violence they live with, its even in the house even thought Lori says what happens in "Vegas" (the suicide knife). The fact that Andrea "can't be one of the guys" it takes strength to kill with a knife... Rick looks at the two dead walker cops and "remembers him and Shane as partners" then goes back to save him even though he just tried to kill him?
