Thanks for the explanation. I do understand your concerns.

And I'm okay with the part about not interacting directly and not being in the same thread.

But I was wondering, when you say each could be vaguely aware that the other character is "around somewhere" -- I'm not sure what that means? I was definitely planning to take both characters to Tol Sirion. And each of them would certainly know that the other was on the same expedition. They couldn't be vague about that.

I can definitely manage it so that they don't address each other directly through tags, but are they allowed to notice each other indirectly and be somewhat aware of what the other is up to?
