[Oh, that definitely looks like a personal issue. Ren notes it for his own reference - and that abrupt change of topic - but for now, lets things move on. If it turns out he needs to toy with that later, then there's no use wasting all its effectiveness now when Phos has been civil enough.

...He can't help but wonder whether to mess with them when they ask about this station, though. It wouldn't technically be lying, considering what the people of El Nysa apparently treat Thesa as...]

Yep~ [Yeah, he's going the messing with Phos route, though it's pretty much impossible to tell that he is - his upbeat manner doesn't change in the slightest.] You can hollow out parts of planets to make buildings, you know, you don't have to build them on the surface. So you can't really see anything from here.

[Or, you know, it's a space station and he's conveniently talking about things that would imply this is a building under the moon's surface without actually directly saying that it is.]
