I'm deeply, deeply worried for Marten. He might be able to repress everything right now, but after 4 or 5 fancy beers, he'll be having himself a tear-stained, embarrassing evening. Poor Marten. Our author is setting it up perfectly! Marten never even answered Steve's question satisfactorily--of course he's not okay, even if he's laughing.
On the other hand, I'd love it if he could calm down about this. Imagine, the same day (in QC time) you begin to hanker for some sexual contact, you get it? Sounds like Jeff-ex-machina to me. A normal shy guy who has little sexual confidence would not be so lucky; try a gap of months (or weeks, if you're lucky). He's basically living in a storybook world, where casual sexual partners grow on trees. It's weird, but the fictional people who mope about not getting any action get many times more action than their real-world equivalents. And yes, he's looking for a relationship, but it would be nice if he would at least thank his maker (well, thank his author) for making life so bloody easy in other ways. Seriously.
