Hi, Joan! Maizie is such a cutie! I feel so bad for her dad's murder and it's wonderful she has a mother figure in Savannah. Charlotte would definitely know they've been dating then, yes? Or at least eventually figure it out.
Charlotte would definitely see a little bit of her younger self in Maizie .. you know, aside from the whole end of the world thing. I could see Charlotte trying to teach/show Maizie minor things. Also, Charlotte wouldn't hold back at all from laying everything out in front of the teen. She feels that the better someone is prepared and educated the easier they can handle anything ... especially teens.
