^ Good post, Blue. I think you nailed it. Add to it that Andrea is looking for some kind of normalcy and intimacy. She thought she found it with the Governor and now she's having a hard time letting go of it even though doubts are starting to come out as evidenced by the knife scene.
Also, someone told me the Governor was awake and saw what Andrea was thinking of doing. I didn't notice this. Did I miss it or was I misinformed?
