As strange as it might seem to some, Jon hadn't minded his time at the Sphere terribly much. Sure, it had been an adjustment to being in underwater domes, and there had been aspects of the place that he really hadn't enjoyed (everyone in the place being able to see his memories comes to mind), but as a general experience, it had been better than Westeros. The Sphere had allowed him to see family he never thought he'd see again, and he had found happiness there.

Speaking of said happiness, Jon breaks into a smile when Llewellyn mentions Inesa's name. It's a natural response at this point. "I've seen her." He's done more than that; truthfully, he'd gone to her home and returned to the one he was assigned. "She mentioned that you were here."
