According to Silver, Idia always gets flustered around him: we see them interact in a vignette where Idia compliments Silver’s “totally protagonist dialogue”, saying that he wishes he could say similarly cool things.
Silver encourages him to do so but Idia explains, “It only works when you say it.”
Idia happens upon Silver sleeping in the school’s courtyard and comments, “Wow, he’s seriously handsome. He looks like a prince when he’s sleeping.”
Idia insists he wasn’t watching Silver as he slept and again marvels at Silver’s ability to deliver “the most impassioned caping I’ve ever heard this side of a chat room”, telling Silver he is “so cool.”
Silver says that Idia’s tsum ran away the moment that it saw his face.
In a Glorious Masquerade voice line Idia says, “Silver looks so gallant no matter what he wears. Even this getup makes him look like some noble knight.”
In a parallel Glorious Masquerade voice line Silver says, “Idia mentioned that Fleur City had ‘extrovert energy.’ It’s incredible the way he can pick up on things you can’t see like that.”
Silver also says that Idia is intelligent, giving the example of Idia being able to concisely summarize what it was that he wanted to say during his birthday interview.
In a birthday vignette Silver says that he hardly ever saw any townsfolk when he was growing up and had no idea what their daily lives were like. Idia responds, “So you didn’t have any contact other than your family? I can kinda relate to that.”
Silver invites Idia to join him and Sebek in training but Idia refuses, and again comments on Silver’s “whole dashing prince vibe.”
Silver and Sebek brute force their way into Ignihyde to kidnap Idia to Diasomnia for rehearsals of their Glorious Masquerade performance. Idia says that he will be upgrading their precision security system but
Lilia responds, “When someone tightens their defenses, we have but to increase our offensive force.”
