There's definitely a moment where Inigo looks at Gyousou with instinctive surprise at those last words, because.. wait, what did he just casually slip in there? It's not even like he can ask about it, since Taiki is here now and he'd feel like it'd be more than just kind of rude to do that right in front of him! So Inigo is just left to wonder - what mistakes? How deep does this suffering well run?

Thankfully he manages to shove the surprise down and instead smile brightly at Taiki the moment the other puts down the food. It's fine. This is fine. Everything is cool.

"Hey, I can grab the food next time. You don't have to do everything!" He instinctively reaches for the food before realising that dangit, he's in the presence of a king and can't just act like a total caveman! He quickly pulls his hand back and gives Gyousou a smile instead this time. "You should pick what you want first, milord."
