This whole interlude is made of Yuri being only ever half certain of what Yurio's reaction might be, and only ever maybe close to half right in those guesses. Never quite expecting when he'll snap, or tense, or look like he's about to kick Yuri off the stool. Never in a million years would he have guessed the quiet request to stay, or the intense focus on being taught how to hold chopsticks. Or this, either.

The quiet way Yurio seems to hold still. Like he's not so much reacting to what Yuri was telling him about Victor enjoying his birthday surprise, as he was taking it in and trying to process it. Maybe like it's another language or something he wasn't sure he wanted to know. Or maybe something Yuri shouldn't have shared. Given the first bark of surprise only seconds before his own last words.

Instead, it's just that small single word first. Dug from somewhere deeper in than it sounds like should be able to be held in two syllables. Small and ... uncertain? Is that it? Is it that Yurio seems uncertain if that's the right word. Or reaction. Or how to. Yuri looked at the boy, quietly, as he took another bit of his food and Yurio seemed to still be reaching for just what to say or how. Which gave Yuri the oddest inspiration, words coming out before fully thought.

"I can tell him you said hello." There's the smallest uncertainty wavered there.
Not that Yurio had offered, or had said. But. "If you want."
