This time Yue turned the rest of the way to actually face Fai, one pale brow quirking just a little in inquiry. "You know you have somewhere to go, but you don't know where. Or what." Though his voice was entirely expressionless, the look on his face probably said more than enough about what he was thinking about that. "Dare I ask if you know why you're going on this unspecified errand?"

Hopefully it wasn't something as potentially suicidal as their mission to the rooftop a few days ago. And it was more important than exploring the staircase that might lead them to some answers? But if Fai didn't even know what it was, then...well, unfortunately for him, Yue wasn't about to just let that pass without comment.
