Inigo's gaze drops for a moment - not necessarily looking sad, but mostly just kind of shy in that way Inigo sometimes does.

There's still some sadness and even more complicated feelings, but he's shoving those down as far as he can, letting out a shy little laugh before he manages to turn his gaze back to his friend.

"Is that still your dream, then?"

Does Inigo realize Fang Duobing was turning this towards him? Of course. But that's why he's pushing it back towards the other so quickly. As long as Fang Duobing doesn't look too awkward about having to be vulnerable, then it's fine - Inigo wouldn't turn it back to him if it felt too delicate. But it's nice to hear Fang Duobing speak of himself, and Inigo really does not want to think about his own dreams and all the nauseating feelings that brings.
