One morning they wake up together and are lying there in comfortable silence when Etty scoots up and kisses Nona.
To Bella, she explains matter-of-factly, "I'm who Celo is in our world. I'm not a nymph, I'm a sorcerer's daughter, but he was the same way with me that the man who planted Celo's garden was with him. My father kidnapped Etty and put a curse on her and then we killed him."
"Well, I'm who Etty is in my world, I guess, and I'm a subtle artist - I have mind magic, I don't use it without permission except that I can always tell if an unshielded person is around - and me and Celo go to school together. Although we don't share any classes."
"...I think calling myself a scholar would suggest it's less common than it is to go to school where I'm from. I'm a student. I'm going to be a mental healer." She pauses, peering at Etty. "I... haven't taken any classes on mental healing yet, but you seem to be not in great shape, and if we're as alike as we look, maybe I could do something?"
"An interplanar bar. I guess stranger things have happened. It just appeared to you?"
"She looks like you could be siblings," decides Bella after a long look at both faces. "Awfully similar siblings." She turns to Etty. "We should compare life histories."
Bella goes first. Parents, little town in Blackwater, subtle artistry, school, introspection, her questions -
Heh. And school and her inauspicious first meeting with Celo and the business with the elves and what she's at liberty to share about the business with Callahan. That's pretty much the story of her life.
Etty's story is shorter and less pleasant. Parents, unremarkable upbringing, figuring out that she only yearned after women and not men, getting picked up by a giant owl and cursed, meeting Nona, turning into a swan (she demonstrates), the hurt and the violation and the terms of his immortality and their ultimate victory. Poking around at sorcery, flying over the countryside looking for home.
