The flashback was the best part of this update. It could have been even better if the animations had been done for that section of the update instead of the silly bathtub scene.
What I really like is the flashback gives contextual background for Sophia being open to having sexual relationships with Sam and/or Dylan. Especially Sam. With them, she can switch roles and be the mentor and give them a first time sexual encounter to cherish. Instead of them being hurt or embarrassed or disappointed or a combination thereof.
The flashback sets up a good parallel between Sophia the teenager and Sophia the adult. An added bonus is she and the boys will be at their sexual primes.
The sad thing, of course, is how long it will take to get there.
