my theory is Mayan is being upgraded to a "main-dame" to remind the MC he is not a manipulative asshole but a genuinely good guy and Mayan is his guilding light back to the land of love and caring..because if you are manipulative and dominating or whatnot to her..you are basically punching a puppy in the face..and shame on you!!!
I haven't really seen a manipulative side to him in a horrible way. Sure he lied to get the job and fuck all the women but, in my play through at least, he seems to care about them.
The only one my MC gives a hard time to is Jenna and that's because she needed it. Towards the end of the last update he had softened up to her a bit now she's not as bitchy as she was.
As nice as i've played him he still has a way to go before he trusts someone relationship wise. I think him and Mayan are both broken in different ways and could help each other.
She's pretty much the perfect choice for those that aren't into incest or muscle women.
Shit, she's probably going to put Jenna under pressure for my top spot.
