Thy only authentic ending is the one provided here: John and Mary die, John and Mary die, John and Mary die.
Margaret AtwoodWe'll choose knowledge no matter what, we'll maim ourselves in the process, we'll stick our hands into the flames for it if necessary. Curiosity is not our only motive; love or grief or despair or hatred is what drives us on. We'll spy relentlessly on the dead; we'll open their letters, we'll read their journals, we'll go through their trash, hoping for a hint, a final word, an explanation, from those who have deserted us--who've left us holding the bag, which is often a good deal emptier than we'd supposed.
Margaret AtwoodThe cemetery has ... an inscription: 'Though I walk through the Valley of the Shadow of Death I will Fear No Evil, For Thou Art With Me.' Yes, it does feel deceptively safer with two; but Thou is a slippery character. Every Thou I've known has had a way of going missing.
