"Sometimes it's a good feeling that's important," he smiles, his own fingertips beginning to prickle with cold in spite of his gloves. He shifts so that he can follow suit in tucking his hands in under his arms. "Maybe it's silly, but sometimes, I think the lights are like a reminder to be hopeful. Sometimes you are disappointed, yes, but that's also something important. If you didn't have the disappointing times, the good times wouldn't be so special."
His cheeks warm a little more, and Fannar suddenly laughs a quiet, bashful laugh. Oh. He's talking too much. "Sorry, I— I just think a lot."
Not just. It's a secret he's kept hidden, all the time he's lived: he writes. He's lost track of how many poems he's written on the subject of the northern lights, so they bring up many a thought — but that knowledge, he'll burn his throat on lava before he ever admits it aloud. No, that's just for him... even when he feels the occasional, fleeting pang to tell someone. In all his years, it is his best guarded secret.
"No — it's not," he answers, gratefully drawn from his own head. He untucks one hand so that he can gesture along the shape of one arc. "Little electric... Ah, the fucking English — particles? — From the sun, they come to the Earth. Our magnetic field pushes most of it away, but in the north and the south, the magnetic field is the most weak — which is why we only really get them there. And, so, when they come into Earth, they'll hit, like, oxygen and stuff up there — and when they do, it makes a tiny light. So, really, what it's all just... billions upon billions of little tiny lights, and they all come together. And that's what we see."
He turns his head to look at Aiden, and he smiles. "I was told, it's the same as how neon lamps work. How people were able to just..." He gestures back up to the lights, as if emphasizing their size. "It's so big, here. But then these little lights, they're like... they're kind of like the northern lights, but — eh — controlled, you know? Isn't that the most incredible thing? That such smart people could take these lights, and put them in a jar to make something beautiful that they wanted to make. They're so different, but also... not so different. Isn't that amazing?"
Once again, he catches himself as talking too much, and he once again shrinks into himself. With a bashful laugh: "I-I'm sorry — I'm really talking a lot this evening."
