This sneak peek of The Walking Dead Season 3, Episode 7, "When the Dead Come Knocking," picks up from where Episode 6 left Rick (Andrew Lincoln) and Michonne (Danai Gurira). They silently stare each other down, he on the safe side of the prison fence, she with the walkers. The walkers seem to figure out that she's human (the blood smear trick doesn't last forever) and she's left to take care of them on her own.
Carl asks his dad "Should we help her?" Dad says nothing. Rick does not take too kindly to strangers, so she may have to solve this problem on her own. However, he walks away, and maybe he's walking toward a place where he can help. But this would be a good time for Michonne to actually say something, words to the effect of "Are you Rick? I know Andrea. I saw this guy abduct a couple you might know." That kind of thing.
Episode 7 airs on Sunday, Novemer 25 on AMC. Catch up on all kinds of nifty Walking Dead recaps, spoilers, news, videos and polls about Carol, Daryl and Andrea here at Wetpaint.com/the-walking-dead.
