The problem is that Eve is a subject Aya is not willing to openly discuss. It's ancient history to her now and even Eve doesn't really remember what happened to her. Aya would no sooner explain to Eve what happened before she tells anyone else.

As for her being paired up... That would work. I would also like to include Riyaz as well, though, since Aya's kind of been helping him around since he first showed up.
