Darth has absolutely no interest in "coming out of the shadows" and engaging or communicating with staff. Had him on board a flight recently down to Melbourne - apparently. Didn't find out until after we were at the gate in Melbourne and all pax were off. Nobody told us, nor did he even bother to stick his head in at the end to say "how's it going, boys?" or "nice flight, guys".
That tells me something about our leader.
Very disappointed.
