A little clarification, anon. We know that Lilith is Waiter, as in the Waiter that showed up in Capriccio Farce. Riliane reincarnated as Lilith, then Lilith became Postman, whose body was "broken" somehow to make her essentially catatonic, and then Arte gave her own body to Riliane (receiving another one from Lich,) which is how Riliane was able to start talking and emoting again as Waiter.

That's all exposited pretty clearly.

Greek is talking about the waiter that serves Gallerian in the Graveyard Restaurant. We originally believed this waiter was the same as the Waiter in CF, but the timeline of Waiter coming to be makes this impossible. I think the only reasonable explanation is that the Graveyard Waiter is Arte, Lich's claim that he barely knows her aside.
