Interesting. That pose is pretty clearly... sass. Minako finds herself smirking a little at it. It's sort of a response to her usual straighbacked good-girl pose. Not that Chara would necessarily know that.

Hmm, if you say so, kiddo. Minako is unconvinced about that last part. "Well, that description doesn't really fit me, so no. I suppose I am not."

She doesn't bother to question why she seems to know the meaning of the child's sign language. The castle is magic enough to age her up, it's magic enough to translate.

Even the false smile doesn't really faze her. "Sorry to disappoint you."
