Well, the 2 Rick killed in the bar didn't reanimate, so there goes the "everyone has the virus" idea. Shane lying to Lori was awesome. I think almost everyone would have done the same thing. I really think Lori is the root of all contention. Kill her and Shane will be "right as rain". ETA: Oh yeah, "Hey everyone, I think Lori's missing. We need to search the farm!". Um, yeah maybe she took that Ford Taurus that's been missing since noon.
