Why does Sophie need to get her comeuppance?
I've said this once, and I'll say it again, they're dragging on this route for way too long, it should've have ended some time ago, and left our imagination to do the work for itself, but if Azienda wants to do it this way, they can.
To me, from the first boob flash, to the first time without a condom (vaginal), was pure gold, and that's all I need, but I also want to see how the other route (her accepting Zach sleeping with other women) goes. It's lost a lot of steam and is dragging it's feet.
