Her response was very shocking. What was Rick supposed to do, sacrifice himself?
And she seriously needs to stop coddling that boy of hers.
Lori even fails at coddling her kid. In the last couple episodes alone, Carl managed to steal a gun and wander off into the woods and attempt to confront a zombie (which may have gotten Dale killed), mill around the farm and end up in the barn when Rick was about to off the kid they captured, and finally meander so far away he got to where Shane was planning to kill Rick.
Lori just sucks. I will applaud when the walkers devour her.
