bro, you know I want more, too
. I'm just stating the thought process.
In this update, they wanted to bring Nadia to MC's villa. My gut feeling is that Omar wasn't there in order to show how Rabiah is changing back to her old ways (being more liberal). Nadia doesn't like him anyway, so she's happy. So here, no sharing scenario would make sense. Even if Igor was around, I don't see that being something they jump into in this scenario.
They wanted to show Shani and MC getting close again. Definitely not a sharing scenario.
They wanted to get back into more of Yuna/Ivy's history. Definitely not a sharing scenario - no other person even knows about her home/hide-a-way.
So, I see what you're saying... and I definitely want more of that. But they decided what things they wanted to touch on here and that particular kink isn't compatible with these scenes, IMO.
