I thought the zombie in the well scene was some great film work. From the camera work, to the palpable disappointment after things went wrong, that was an impressive scene.
And I'm not sure what to think about the house that Daryl found, and what that's supposed to mean. It looked like he found a little cubby hideaway that Sophia(a child at least) could have been sleeping in. But then they just kinda dropped it and didn't touch on it again. When he talked to Carol and gave her the flower, I was expecting something else being found in the house that would give us a clue about Sophia.
