Whatever concerned Himeka about the notion, it doesn't seem to strike Estinien in the same way. It isn't that he's completely disinterested - that sounds curious, to be sure - but he honestly is more inclined to dismiss it as a coincidence. So many other weird things happen to their star. Why shouldn't it be the same elsewhere?

Estinien is fairly comfortable not understanding things he considers outside of his purview, so while he looks a bit perplexed, it's not on account of any sense of urgency or thirst to figure out the root of the contrast. He's sure the more scholarly types from the Scions would have better theories, but...

"I suppose that isn't surprising, given that mine own world has undergone similar... rejoinings." Or similar enough for Estinien. "Mayhap they were once connected parts of a bygone era? Or perhaps 'tis simply a law of the universe that what can be sundered can also be merged."

If Himeka didn't mention it to him, he'd assume it was because it isn't any weirder than everything else going on in this place.
