I think Monica does well, in trying to build bridges between her and Naomi, since it seems that with Sofie, those bridges seem completely useless.
But Naomi's behavior, in my opinion, does not stop being a correct behavior, civic and little else.
A situation very distant from what could be a comfortable and normal situation for two roommates (you will see that I do not even use the friendly word)
PS: anyway, the behavior of Sofie, in these last two or three days is being quite strange, even Naomi, has been surprised to ignore Sofie, when she returned for the last time to Sofie's room.
