Hi. My name is Croix

I haven't quite figured out Croix.  I imagine I'll spend the rest of my life trying to figure him out.  He often proclaims himself to be shy.  And acts very shy, hanging close to me, or clinging to my leg, or staying on the outside of what's going on just observing.  But there are times he just pops out and says "Hi, my name is Croix"  to perfect strangers.  I think in regards to the strangers part I prefer him to be shy!
