After Rick chastises Tara for her part in saving Spencer, she has the perfect response for the sour-faced, rasping Rick Grimes. If in doubt, a middle finger always comes in handy. It's rare that anyone ever disrespects Rick, and if they do then they usually feel the wrath of the grizzled Grimes. Clearly that didn't faze Tara as she promptly flipped the bird. In fairness to Tara, there have been quite a few times during The Walking Dead's run where Rick has needed bringing down to the earth, and this was yet another one of those moments.
