Smiling or not - Doesn't matter. Maybe half a smile, or a shy smile? She's going to be serious, but know how to relax herself when around her group. I didn't even think of the name, but guess your right. x) The teasing is also what I was referencing to. :3 Oh, and I didn't think she'd join so young as 12...but it could be even better. If she joined at 12, it means one year after she was exiled which would make sense. If your character found her and found out who she was, he could have took her to his group and convinced the leader to accept her in without telling him who she was. Incidentally, maybe he did tell his captain who she was which was the reason he accepted such a young child in, but died with his secret leaving your character the only one to know?

When you say mercenary knight, you mean the Wyvern knight? I didn't think she'd (Female to answer your question, 3 males 3 females) be a mercenary. More of a Wyvern Knight that, for a reason I need to define, decided to pledge allegiance to Renais. She could be considered Mercenary, I guess, by some.
