My dad likes you. My mom knows what you are. My brother knows what you look like. My younger brother may know a bit, haven't interrogated him yet on that.
But I know nothing. So it's not the "whole family". :V
*does not find it suspicious at all*
My mom's an expert at looking through even the thickest of smoke and mirrors. She can tell lies, and deduce the truth in seconds.
My mother somehow managed to find out the age, and other various details of Jean just from a glance.
That marks two people who know who Jean is better than I do.
