But the way Faye asked didn't sound like that. At that moment, it probably sounded more like "Do you prefer bread or rice?" - a conversational side-step into trivia. Faye hadn't mentioned Bubbles moving in or anything lately, and Bubbles knew her initially as a mechanic, so for a moment, Bubbles took it as a purely mechanical question.
It wasn't meant that way, of course, and once the minor miscommunication was cleared up, Bubbles clearly got the idea. But it was a perfectly plausible one-frame communication glitch which served narratively to show that Faye is determinedly focusing on the practical.
