Well, we already know there's a threesome so you're already halfway there to having your own
paradigm shift
When Josy still expressed her interest in still being a HOT, this was
before they knew Patrick was there and
before Josy needed somewhere else to stay. It became a means to an end later which Maya accepts, but in the heat of the moment immediately after feelings humiliated, Josy expressing that interest wasn't tactful even if it she was caught off guard and she was expressing herself genuinely. You can even tell she's cagey about saying this because I think deep down she knows this is bad saying this given what's just happened.
Again, not about control, just that it hurts her to hear that her gf still wants to be part of the group that she feels played a cruel prank on them. Anyone in her situation would feel that way in that immediate moment when things are still raw.
