I'd think it would come down to continuing in whichever language gives the most fluent results, the biggest common denominator so to speak. But is there a rule? I haven't heard about one.

I think you are right, whichever language gives the most fluent results. I've had lively discussions with friends when, later on, I've realised that we've just been constantly switching back and forth between languages. A couple of glasses of wine makes the transition easier.
