This is a lot less angsty than I thought it would be, which is nice. I was worried that the scientists would be upset at Chika for messing with their experiment/Hiro/Praha, but they seem to be curious about their interactions instead of angry. I still feel for Chika, though - it's like a learning experience for both of them, on how to love.
I find the scientists' attitude much more realistic (to the context), the robot was sent out live a life amongs others, they are observing the situation and analyzing it without disrupting it... Like real scientists would do.
