I haven't been watching the live feeds or reading updates since the nomination ceremony, but I feel like this season has been evolving away from newbies vs. veterans, I think there are definitely splits in the veterans and I doubt that they will all stick together. I think alliances and complex relationships will form between the newbies and veterans that it makes it not straightforward newbies vs. veterans.
As for other seasons, I feel like when veterans play against newbies, veterans are so insistent to make alliances to keep the target away from them, and I think newbies are fine joining them because it gives them protection as well. I also feel like these alliances don't really run deep into the game and veterans start to turn on each other. Big Brother is very complex and if a newbie plays it well, they can beat a veteran. I don't think it is a matter of being star-stuck, just people playing strategic games.
