I do not know, of course it is strange to have invited a friend outside the circle of her best known friends...Especially one that is far from the circles of LB's acquaintances.
It is certainly rare to see her in pajamas. Not even in Krasnoyarsk did she ever put on pajamas to sleep. Either someone made her angry on the phone by making her pass the desire to do anything or is a veiled message (but not so much) towards us.
It has already been explained that Paul already knows everything about LB.
What I'm wondering is why Paul doesn't leave Leora permanently or vice versa why Leora doesn't leave Paul...
I wouldn't dream that big though. This friend of Leora is not Malia and she doesn't necessarily like doing these things in front of the cameras. And they don't necessarily have such a high level of intimacy.
