Hm... Let's see...
For Ciel, I'd go with... Very few people know that, in the 21 years she was without memories, she grew close to no personality. So when she recovered her memories recently, she retained a lot of her 8-year-old stubborn Ala Mhigan kid personality traits. Everyone probably just thinks she went from weird to weirder, though.
As for Wayward Sage... Despite being a Roegadyn warrior with a borderline arrogant attitude and feigned disinterest for all the things, she's extremely weak-minded and low on self-esteem because of her twin sister's influence. The only person who knows that is the person who very recently severed that influence and picked up the pieces.
