Yes, it was her father, she said "thanks dad" (in russian) when he left. I don't know if she had her own apartment in Moscow or if it was just her room, she showed it a few times on her social, but it was very nice, very neat with style, very girlish.
About the sitcom, Kami loves shitty tv programs, russian or english, but her english is far better than I thought, listening to her talking to the english guy she met in Kos then in Finland. She is a TV addict, put it on to sleep or to wake up, her mother did so too, so it is a tv education she had - not very good indeed. Kaley, who is younger seemed better educated, better able to move around in the world.
