@@Once In A Blue Moon,
As the kept a quick stride to follow Cat, Colenso couldn't help but to think to himself Wow, I thought she was exhausted. But then again when one is doing what they love, they tend to get excited for it. They stepped into the night, the cold nipping at Colenso whom happily shivered and always found he had a positive relationship with lower temperatures. The dark was almost too much, but almost wasn't quite, and he did as Cat asked, pushing through the bramble and undergrowth and out the other side.
As they moved deeper into the night, Colenso was thinking of the moon, and the stars, and the discussion they just had with Avidity. The sky radiated with such pale moonlit beauty, the stars like shimmering gems against a black velvet bed. They stepped out onto the stone as Colenso thought, If it was as great and beautiful as they claimed it was. As this... Would I give up the existence of everypony here, and mine as well to get a future in which Equestria didn't fall? The question was hard, but he came up with an answer as soon as he asked it, and it was enough to bring the shine of tears to his eyes and take away his common thoughtless smile.
Cat snapped him out of it, and he quickly wiped one of his forelegs across his eyes to collect the tears. He looked over at the binoculars and nodded, adding, "I wish I was as skilled at math as Alto." Even though he didn't understand a single thing about mapping or figuring out where he was, he appreciated her passion for it, it was very complex work. The mountains, landmarks and stars. He really liked it here. Just a wandering mind again, he had to stay on topic, keep his focus. It would be rude of him to feign interest. She began to mention the world being bigger than what they knew, and broke out into a little diddy before recovering in an embarrassed fashion and continuing the point. He was well known for long periods of silent listening before responding. This was no exception. After she finished, he looked to her and commented, "You have a habit of impressing the hell out of me, Carto." Gesturing to her things, "I mean, look at all this. Patience, everything having to be just exact. The skill required for any cartography is intense. This is your passion too. Sometimes I find admiration in unexpected ponies, but you aren't unexpected." He realized that it could have been misconstrued as affectionate banter, but he hoped she only took it at face value. He had no interests.
Then, turning his eyes to the sky, he took on a more intellectual tone, "You're not the only one that doesn't believe the world is as small as they say. Gravity dictates it cannot be so. The farther anything is from the center the more outwards the tilt of it's stand would have to be in order to stand at all. And fall into what? If the world just had a cliff, we would gravitate towards it's other side." Down to the ground, "You're right. It doesn't add up. It never has. I could just never do the math myself before."
