"No, bug. It's not fair. It's not fair at all." Magnus won't tell her he would have traded his mom's visit for a better day for her, because he's not certain he could have brought himself to do that. Plus he knows that by the time she's six she's fine with it, so... at least that's something?

But she shouldn't have had to see Olaf at all.

"Someone really stupid once told me that life isn't fair," Magnus says instead. "And that the sooner I realized that, the happier I'd be. But I'll tell you what, Sunny. We can find a way to make sure that even when it feels like it's really unfair, there's something we can do to balance it out a little. Okay? Like how when people were being really unfair to me after I lost my mom and my house, I'd make myself feel better by, um. Taking their money and using it to buy myself a really nice lunch or a change of clothes. It didn't bring me what I really wanted, but it made me feel like I had some kind of control over some stuff. You know?"
