International Man of Mystery

Wait...didn't we already find out that one Greg Cooper was James Bond?  Like a year ago?  That's why he went to London and gave Margo an emerald pre-engagement ring.  Is Lu Ann Skyler playing coy because she doesn't want to watch Margo to kill her in a fit of rage stroke when she brings up Greg's name?  Or is this obvliviousness part of her method acting?
