Even Josy moved to the HOTs house in EP7, which is one episode. But I don't know if all that will happen yet in EP10. That's why there are 2 possibilities in my previous post you refer to. I also consider the possibility for the room to act as a movie theater during Maya's HOTs welcome party more likely, because Sage liked it during the Halloween party too. But Maya will be with Josy a lot and Heather will even be in the room with her. Josy, Maya and Heather will use the sofa bed for watching TV. Pajama parties.
Josy moved so fast because: it was urgent, there was a vacant place and a room to stay & share. She already was ready to do so, but she took Maya's side at the HOT's ceremony. Heather, Maya, Josy and MC ? Will they ask Heather to wait somewhere else while they fuck and have fun?
This assumes that Heather will know about their three-way relationship, and Heather is unlikely to break up with Tommy so quickly and will most likely tell him everything she knows, or he will ask her himself, given that he knows who she lives with. Here we can only speculate - how the walk of shame will end and whether we will have any options - to tell or hide the truth and what the DPC has planned for the J&M branch at all.
Josy's beautiful underwear is clearly dressed specifically for the occasion of a date/mini-party/whatever else it would be. We don't know is there anybody else in the room at the moment. There're could be Maya too, but maybe not. What about Maya's preview, when she come alone to (probably) MC? DPC probably picked the most neutral renders for both scenes to hide the subtext and meaning of what is happening.
I also think that TV and watching it is the last thing MC and Josy think about in that scene. Even if we assume that TV is there. I don't recall that Josy is a big fan of watching TV, and Maya watches mostly movies.
The Maya's TV scene was very touching, especially knowing at what moment the MC made Maya this gift. But repeating such a scene would seem to me to be a bad choice. I would prefer something other than watching TV, it's not very romantic if all three of them are there at the same time and it's very doubtful in principle if only Josy is there. MC can always invite Maya to his room, he has a TV, and he even planned to do it back in season 2.
Maya tested the waters. She thinks about moving there and want to know as much as possible before she will decide. That's how this dialog looks and feels like.
However, I am a firm believer so that the MC will live with his chosen LI or LIs. Maya herself implies in EP6 so that the MC's room is also suitable for two people and in EP7 Jacob mentions so that he and the MC are ambassadors. In EP4 Sage Branch mentioned Sarah so it would be nice to have a guy in the house.
What if Heather becomes the HOT ambassador to the DIKs and the MC becomes the DIK ambassador to the HOTs. Sage says to the MC in EP7 so he better not be president and that would bring more fun. That would fit, another DIK would then get the room.
But Sage also said so the presidential title would fit well on his resume. Well, the MC already has the Presidential Suite at the DIK Mansion.
They can't "live" somewhere, except the frat they pledged, as far as I remember it right, it's prohibited by the rules of both frats. Especially when it comes to male/female moments.
They can stay for night, as some of DIK's and HOT's members do from time to time, but not move, live, etc. Spending nights, etc - no doubts. It may happen periodically with any or most LI, hm... probably with except of Bella.
