So if the intention was to negate the series by attempting to rescue Laura and thereby obliterate her death, and the true owners of the house were used to indicate that Cooper was no longer Cooper (hybrid or otherwise) and had crossed the fourth wall into reality (though Tremond/Chalfont harken to convience store characters), why wasn't Kyle MacLachlan simply credited as himself?
I don't accept the premise that "Cooper had crossed the fourth wall into reality".
In reality, that house is in the suburbs of Seattle. It sold a couple of years ago.
