Yeah that works, given Mirror’s back story of being on the move a lot, it’s possible that she ran into him after he had been ejected from his family business. Perhaps she was someone who took pity on him and offered to help him out as they travelled to the next town or something and the form of payment she wanted was to document him.
It took me a moment to understand what I had read. But yeah, I suppose Mirror would be curious on how your character would be alive, and why they would carry a part of their own brain around. She would be both disturbed and intrigued.
I for one am perfectly down for the first idea, since my character is about protecting those who can’t do so themselves. Though at the same time I must resist my temptation to go for the option of naming the group, my attatchment would be too much.
I have yet to come up with the looks of her, still in the character design process and I’m very picky on how I want my character to look when I draw them.
