I was joking before, but it really is odd that Therese left like that without asking for her share of the house, either by Anthony buying out her share or selling the place and splitting the proceeds. Since Therese was a high-powered career woman, I assume she ponyied up at least half the down payment and mortgage payments. It's weird that someone we've been told over and over again was a money-hungry witch wouldn't get her money back.

Of course, since Lynn is stuck in the 50's, it may not have occurred to her that Therese would have contributed to the payment.
