Well, that would explain it, and while Idia has gained Ruggie to do that (in exchange for future favors...), he's still curious, "Oh yeah? Who?"

"I've researched it for writing." Don't ask what writing! Considering he's now eaten that red candy there's a good chance that he'll just come right out and say it thanks to the side effect of a lack of filter. It wouldn't matter to Idia now, but Future!Idia is not going to have fun with how much he's going to be telling people stuff today...
