I confess, I squealed when I saw Lumen show up. Very well done! I loved how conflicted Arnbjorn was and how he just couldn't resist. Also loved the little touches of Lumen introducing him to something new - wonder if he'll try that with Astrid and that's how she realises he's been unfaithful (not to give you ideas or anything...)

And the guilt at the end, oh the guilt. I do feel a bit sorry for him. Caught between Astrid and Lumen, oh dear. Perhaps the imminent arrival of the Oculatus is a mercy...
