Hard to believe Petra didnt spend Christmas with her dad, he probably doesnt have many left, she is only a 1 hour flight away, she could have flown in and out Christmas lunch.
Clearly a big rift there either with Sam and her father, or Petra and her step mother, it seems to be a long time since she saw him, i don't think he was even at their wedding, when she posted photos wishing him a happy birthday, they were all from when the kids we very little, no recent photos and none from the weedding. . Plus Sam being so insulting about Gstadd, when Bernie practically owns the place, makes it more likely a rift between Sam and Bernie, i would say Bernie had Sam sussed out from the beginning.. Jay keeping his nose clean and staying tight with Bernie. Someone in the comments on jay's Insta linked to Jay's personal Instagram account, for friends and family only, seems a very active insta. I don't know how anyone can manage two instagram accounts, what a hassle.
