Assuming Zilpha kills Geary, which is something that Delaney failed to do this week, the two might finally run off together and open a bed and breakfast on Nootka Sound. How charming, right? (Here's the menu: hard-boiled eggs.) The potential wrenches that could be thrown into this plan: the British, the Americans, the East India Company, and even Lorna Bow could all decide to kill Delaney before the series ends. Also, let's not forget Bryce. He's up to something.
Of course, all this speculation is rooted in the idea that Delaney truly pines for Zilpha and wants to build a better life with her. His devotion to her is one of the few character qualities that's remained consistent throughout each episode of bloodletting, blackmailing, and saltpeter stealing. But, the more time we spend with Delaney, the more we learn he's loyal to no one. While that's allowed him to get an advantage on some of the most powerful people in London, it also might be his undoing. That is, if he doesn't choke on an egg first.
