She shuts the book.
"I'm seriously tempted, but I think there might be long-term problems if your parents didn't trust me to respect their decisions about that sort of thing; they might decide that we aren't allowed to hang out, or to do so unsupervised, or that you're in too much of a hurry and it's unhealthy and you shouldn't be allowed to have the anti-time-slidey spell..."
"And I think that would be worse than you having to wait for me to figure it out on my own."
"I'm just worried about what writing an entire story leading up to your self-insert being eaten by a dragon implies about how you're feeling. I could go ask your father if I can bring you back..."
"I am assuming you knew how you were going to end it when you started it."
"I think I will try talking to your father. If he's not with your mother."
Do you have a moment?
Is Miriel with you or should we continue this conversation in person?
I'm sorry about that, I wish there were more I could do. The thing I wanted to discuss is possibly letting Fëanáro come back to the island with me when I go back first thing tomorrow.
I'm not sure this response is going to get him to regret the right things if it just goes on long enough.
...I'm having trouble thinking of a, a neutral way to put it - um - he doesn't have the maturity or, or general emotional resources to consistently consider being polite and making compromises to be desirable in itself, the thing he notices about situations is mostly whether what he considers important is a strong factor in decisionmaking. And he doesn't know what your internal decisionmaking looks like, and finds reading people really difficult, so his most available test for whether what he feels like he needs factors in at all is whether he gets it or not. I think it would be entirely reasonable to impose conditions or something, especially if he hasn't apologized to Miriel yet, say, but right now his understanding of the situation is that you're hurting him for no reason and the best reason I was able to explain to him for why I wouldn't just carry him back myself is that this would get worse if I did that.
