I don't think Russell connects Eric with the crown either. Russell has been pillaging from humans for centuries. Remember, they don't think of humans as anything more than dinner or items to use for their purposes. Russell probably didn't think anything of Eric. Certainly not enough to keep tabs on him.
Eric hadn't been turned yet. Russell had no way of knowing Godric would turn him later.
When Russell said, "Show him everything," and he mentioned to Eric to please keep his manservant happy, I think "Show him everything" was code for something else.
Newbies always welcome!
I'm not the Welcome Committee or anything. More people always means more to discuss & the thread gets bumped up.

Plus, it's nice on such a long thread to be acknowledged and feel welcome, instead of feeling you have to lurk around in the background.
