Once again, how? Carl would have to keep tabs on her, or she would have to confess. If that becomes an option for Patricia to full around with another man with or without Sophia's involvement, I guess we would have to see how it plays out.
But I don't see Patricia wanting to have sex with another man without Carl's permission. She has almost a perfect life.
Firstly it appears that she and Carl are happily married with an active sex life. Secondly he is rich enough that she lacks for pretty much nothing financially and has a stunning house with pool in a place with great climate. Thirdly is the fact that their relationship is solid enough that he will let her fool around, knowing that she will keep within limits.
Patricia IS a tease. She will happily fool around with Jason and Heru, or with Dylan or even with Sophia. But I think she has clear boundaries which she won't cross. Ad for those that would try and push her beyond her boundaries, sh can go all Desert Eagle on their ass!!
We know from the early stages of the game that she thinks her big sister is too uptight and unadventurous. I think this partly why she wants Sophia to loosen up. There might also be some genuine sexual attraction there as well. Add to that the love and affection that clearly exists between them and I feel that Patricia thinks she can fool around and have a lot f sexual fun with Sophia yet knowing that Sophia would never hurt her.
Others have previously spoken about how that, although Patricia is initially a sexually liberating influence on Sophia, eventually she might become a restraining influence on Sophia. Patricia and Carl have a good enough relationship that they have even talked about her fooling around, but with clear boundaries. This is totally meant as a contrast to Sophia and Liam that completely fail to communicate with each other in respects of sexual wants and needs.
I have said before I think s a consequence of their marrying and having kids so young, with hints that Liam was Sophia's first serious relationship (ignoring her college sexual awakening). So Sophia can't draw on that experience of previous relationships. She has defined herself for 17-18 years literally as a wife and mother, and has until now never faced up what HER wants and needs are. So when she will eventually go off the rails she is likely to do it big time. Hence probably needing Patricia to try to prevent her going TOO far.
