I totally missed that detail, and was wondering what happened to that subplot. Presumably yes, it will come up again.
I need to rewatch, I binge watched with English dubbing, now will go watch with subtitles only.
My theory about Greer is that she is going to be in role reversal with Leith. He was a penniless non titled entity, and now she will be. Maybe she'll get a job as his kitchenmaid.
