I was surprised by how intelligible Joe was last night and he seemed to be trying to give honest answers. I thought it was interesting that Theresa kept interrupting him and saying "can I talk?" as if he was preventing her. It seemed like she was trying to hide things and say half-truths still.
Just from the bit I saw last night it seems like he might have at least a little remorse for what he did, or at leastunderstand the importance of being honest, but she still seems to be in deny and cover up mode.
