I'm not entirely comfortable with the way he brags. It could well be that he wanted to brag about the higher level of connection he had with her. Saying that, he's resorted to dating now (from SA) and the way the conversation evolved it was believable. I must admit, the way Pola was in her early days, I'm not sure she'd totally say no.
I do recall asking what that patch was but don't recall her saying what or why.
If she did/does then that would explain why she'd have an implant and then cover it with a plaster.
