SG,
Oh, but then we have a REAL conundrum.
Have you forgotten the TARP that BC picked up for NC to use while painting? Why on earth would he pick up a tarp for NC to use while painting, if he thought she was already finished painting? Yes, this is circular logic. Interesting and an excellent point about not calling JA when she was "missing". But, her car was also there, and she did not run to JA's house.
Now, we don't know for sure, but as I mentioned previously, I make repeated calls to my wife's cell if I don't know where she is, and she is supposed to be somewhere. We have not heard that this is the case, yet. BC also picks up a tarp for painting that he does not even know is happening? At the same time, he does not call JA, nor any of her friends as far as we know.
