Ow, his eardrums. Ardyn flinches lightly at the sudden increased volume from the younger man. Well, some people could be surprised they were related - since they looked nothing alike, for one - but usually the reaction wasn't quite so dramatic.

His amber eyes trail him as he paces and seemingly processes this new information. What he says next though has Ardyn furrowing his brows in confusion. Ancestor? Founder King? Just like his statement was a lot for Noctis to unpack, that alone is quite a bit for (this) Ardyn to take in.

"Yes, Somnus. A Lucis Caelum, same as me." That much has to be clear. Right? "He..." the man starts, but pauses as he tries to think of what to say. What he's feeling. "So, the gods chose him as king." He isn't surprised, necessarily, but he is a bit seemingly disheartened. Why would he not...?

"If what you're saying is true, anyway, and you're from Eos' future."
