Well, I assume the crime scene folks will have some of his DNA to test... Will she then inherit some power in the firm as trustee for Will, Jr.? Seems doubtful.
Not sure what a pregnancy will add to the mix... wouldn't they just probate the will, give her his money and say bye bye? Are they going to feel a need to "be there" for Will's kid even though they barely know, and probably don't like, the mom? Or just because she seems nuts will they feel an obligation to the baby?
Saw "Will" on Letterman last night. He seemed happy.
