For those who have played at least up to the Bikini scene: do it again, man.Your Sophia perhaps. But flirting more wouldn't have been in character for those of us that still play more or less loyal to Liam. Remember Nat is still on the GW route.
For me it's the point where Sophia "broke" free or where we saw the real Sophia. She glides easily, feeling safe, towards a total lack of inhibition. Let's not forget it wasn't her husband there.
My message was that we are different, that what is hard for one is easy for another.
