Try to explain the finer matters of real estate holdings to the Tuatha. Of course, he knew this was something different, something that meant even more and even less, but he couldn't get her to understand either side of it. "Even were I not here, this would be yours. Even were I not to wish to allow you entrance, you would be able to enter. Even if I wished for you to leave, the choice would be yours, not mine, for while the rest of the house is mine, this, and the entry point to it, is yours. You need not knock. You need not ask favor."
He doubted it would help, but he could not give up the point yet, not when she was still at least somewhat interested and frustrated by it.
There were more important matters anyway.
"I think you are not well and that the cure comes at a cost, one that, if you were well, you could shoulder, that, if after recovery, you wish to shoulder again, should be your unquestionable right. I will defend your wishes against your people if it comes to that, but we cannot yet be sure of your wishes." That he did not seem disturbed by her scar meant little. He tended also not to be impressed by her beauty, natural or otherwise (and his caring about the otherwise was only in his appreciation of her imagination and skill, little more, for his own imagination seemed to be lacking).
Things were shifting quickly though, and it was not surprising she soon sake down in exhaustion or confusion or some related strain. He kept his distance now, did not reach out to her again, for she had already pulled away once. "Fionn, I do not yet fully understand what happened that night, but I do believe it is more complex than it first seems. In fact, I think there were multiple parties and even powers at play and much of what we saw was just kindling for that fire. On that night, we had to act in haste, in reaction. Now we can stop and examine things. Your health and recovery. What is to come. But you can't try to handle it all at once. We need take the smallest steps we can allowed to take. I worry that they won't be as small as we need, though."
