AMC has unveiled a sneak peek at Sunday night's episode (""Better Angels"") of The Walking Dead -- the penultimate episode of season 2!

The clip shows Rick, Shane and the rest of the remaining survivors -- which, as viewers know, no longer includes Dale -- preparing for something big and moving into Hershel's house.

What are they gearing up for? Well, we'll all just have to tune in Sunday at 9/8c on AMC to find out!
