Previously on Haven! Mara manipulated Duke into letting her off his boat. This has historically been regarded as a Bad Move. Dwight keeps getting manipulated by Charlotte and not wanting to admit it, which is also a Bad Move, though possibly not as bad as Mara. Insufficient data, which is our current and perpetual refrain. And now, Vince's as well! Oh, and Mara managed to seduce Duke.
We'll take it, apparently, from the morning after. Where Duke is already dressed and Mara is naked and using her sexuality as a weapon again. Some more. I'm honestly pretty skeeved out this ep by the extent to which that's portrayed as both the natural inclination of women (I mean, there's good reason for that in our society when you're a woman working to ensure power over men, but still) and portrayed as a horrible thing. But we'll get to that point in awhile. The main point here is, Duke is feeling vulnerable and therefore, dressed and heading out after the aether rather than hanging around for cutesy morning-afters, or the second bout Mara tacitly offers, or anything else. You can just assume that every time we hear about assumptions the boys are making about each other's motives this ep, we're sitting and swearing about TALK TO EACH OTHER. Duke thinks he knows where Dwight and Nathan moved it! Duke, Mara is playing you and using someone else to do it. Duke. No? No. She keeps insisting that she's in this to fix Duke and for the sex, which is kind of fucking ridiculous given her early behaviors. You know, the ones where she murdered and assaulted at least a dozen people in her attempts to get back through the thinny and get William? Those? C'mon, people. The remainder of this scene is what I would consider, and I'm pretty sure some part of Duke considers, transparent attempts to manipulate him into believing that she's on his side and wants to fix him. No really. No really, you do believe her, seriously, what is this, remedial HUMINT? Okay, the distract with snark tactic is slightly better, I'll take it while Duke makes his escape. Thinks he makes his escape.
