Hmm...am I crazy for suspecting Nowa is the girl from Wakana's past that hated him for his doll hobby? Those faces she's making on pages 16 and 17 feel oddly familiar with the flashback girl from the first couple chapters. When we see Nowa in chapters 1 and 5, she's normally smiling and not really doing much of anything else besides messing around, but here we see her expressing annoyance outside of her usual smiley behavior and...it kinda fits with the flashback girl. Am I reading into it too hard?
