All the rules of the Troubles are changing in Haven

For centuries, the rules of the Troubles have been simple: Troubles are passed down through family lines—and only through family lines. A Troubled Crocker can end a Trouble forever, and Sarah/Audrey/Lexie may have the power to end all Troubles once and for all. But what happens when all the rules go topsy-turvy?

This was a nice transition episode, one that managed to up the threat from last week's contagious Trouble—and one that deals with this season's themes of morality and sacrifice. We learn that the Driscolls are a famously unTroubled family (I wonder if that incentivizes fidelity among the unTroubled), but that two Driscoll brothers have suddenly developed a Trouble that increases the pressure of the area around them, crushing everything and everyone in sight. Those muggers who attacked Carrie (and, as one commenter pointed out last week, are the fellows from the Barn's Oatley Tap Room—Heavy and Sinister) are back, and they have apparently given the Driscolls their new Trouble, once again changing the rules of the game.

Jack Driscoll, who seems to possess a great deal of sense, decides that he's going to ask Duke to kill him, to ensure that his brother and his unborn nephew will be Trouble-free. I'm sort of surprised this doesn't happen more often—that families don't draw lots or sacrifice an elderly member to the Crocker Curse to end their Trouble. The Crockers have been viewed as monster hunters, but they should be sort of macabre saviors, thinning out the Troubles where people are willing to sacrifice themselves. But it's a moot point now; Duke's Trouble is gone thanks to his killing Wade.

Jennifer and Duke are having rather opposite experiences at the moment. Duke has just shed the last of his family along with his Trouble, and he's wondering if there's anything left for him in Haven. Jennifer, meanwhile, is finding artifacts of her biological family and a home in Haven—and a certain clarity about who Duke is: a hero, someone prone to sacrifice. She's also seeing the harbingers of the super-Troubles, the horseshoe crabs with human eyes.

This may be because I'm a Long Islander who grew up along the water, but I totally love the horseshoe crab harbingers. They're already pretty weird looking beasties and the human eyes are the perfect touch to push them into fully creepy territory.

I also enjoy that this rewriting of the rules of the Troubles has thrown Vince and Dave for a loop. Seeing the two of them off their footing means that they'll be thoroughly involved in solving the town's mysteries—and may reveal a few of their own in the process.

And of course, there is the ending. Is it possible that Audrey killed Nathan, at least temporarily? And, given the next episode's previews, might we have traded Nathan for the mysterious William?
