She brings her sister meals. She tells the girls that Rirosseth isn't feeling very well. It's not a lie. Rirosseth barely moves. 

...but she has a knife, and doesn't have it out, so there's that.

Annie frets but confines herself to asking Lírnith how she's doing no more than once sometimes twice a day even when the answer gets repetitive. She teaches the kids sign language and she reads books.

One of the girls tells Annie, once when no one else is around, that her name is Eliel.

And signs a question: why hasn't anybody rescued us?

Annie doesn't know, and says so.

But they haven't tried and secretly been killed?

Annie doesn't think so.

Annie gets a smile.

She can tell the difference between smiling and not smiling! She has that much practice now! She smiles back.

And after a few weeks she comes downstairs normally - a bit thinner, but not frighteningly so, and apologizes for being sick and almost-hugs her sister.

Annie gives her room. It counts as giving her room if she's a hundred yards away, right?

Yes. That works fine. Annie can stay a hundred yards away except when Rirosseth wants to hear her sister sing and Annie has to go farther, or when eventually she asks Lírnith - have her come see me -

- you can't tell her that you're in horrible pain and will be miserable for the rest of forever. You just can't, she can't think around it. If you understand that -

- I haven't lost my capacity to parse words.

She wants to talk to you. 

Really?

...well, she asked to talk to you?

...close enough. Okay.

And Annie goes and finds her.

"Hi, Annie. I apologize for freaking out at you."

"I'm sorry I upset you," Annie murmurs.

"Sounds like it was really, really not your fault."

Well that's kind of inarguable. Annie shuffles her feet a little bit.

"Are you doing okay? What do you need?"

"I-I'm holding up, you don't need to worry about me."

"And in that spirit I completely ignored you until I was capable of worrying about you without it harming me."

"...okay. But I think I have a stable equilibrium going. Psychologically I mean, in the long term I suppose I need the evil god dead and stuff."

"Do you have a plan to accomplish that?"

"No, not really. I could maybe send her to another universe but then another universe would have her in it."
