OK AS FOR SHIA: He can feel free to hint that he knows exactly what she is and what she's searching for (a demon, and she's searching for her memory, basically-- years and years that she's lost) and he can KNOW and mention to other members about her, should the subject somehow come up, about the fact that she used to have a family-- a husband named Taro and two children-- and that she's at least like 130 years old, but I would really prefer it if details of her family were kept from her for now. She's not supposed to hear the name "Taro" until a certain point in her canon, because it's the key that unlocks her missing memories. It's a hugely important plot point in her canon!

SO BASICALLY he can go on about what she is and what she's on earth doing, and that her next-door neighbor holds the key. I LOVE DOC SCRATCH BY THE WAY...
