I saw my first Norwegian version of the show, having missed the first five. There were a few things of note that differ from other versions or events that were of note.
The sliding door into breakfast. In other shows, knocking before entering is standard but here, the doors slide open. There are some novel ways to enter, in one case two females came in like they were on a catwalk, for example. I actually quite liked it.
Early Banishing didn't happen. For the first half of the game, only one of the four Traitors was sent packing, despite some dodgy actions. The clumsy attempts to find coconut Twist confections didn't focus the Faithfuls on who were Traitors at the time. It did become more important later.
The wrecking ball Forræder. After the first Traitor went in episode 14, in came Johan-Sebastian. He was a Traitor hunter, immediately. He turned on the other two Traitors and quickly becomes the last one standing. He seems to think that puts him in a strong position but it leaves him without any help if things turn pear shaped.
It does when he has to reveal his status to one of the Faithful, Frida. Frida tearfully convinces the round table Faithful to vote him off. Five Faithful remain but the rules state that the game cannot conclude until there are four or less left. Frida went and the last four ended the game and took the spoils. I don't recall a series before where five Faithfuls were left.
I hope I can catch some earlier series from Norway.
