This movie will actually see the main boys barely interact for the first two thirds of it. This is because the 2-2-3 Kenny format would be in full swing, and in addition to that, Stan and Kyle made their new groups of bros:
Stan’s group: Stan, Bradley, Scott, Craig
Kyle’s group: Kyle, Tweek, Token, Kevin Stoley
In addition, at some point Kenny will find out about the charade, and break it off with the boys. He’ll form his own group, which consists of him, Butters, Nate and Francis (two minor characters that will finally get spotlight).
Cartman’s group will last the longest, and he and his new bros will really hit it off with each other, enjoying an amusement park and even having the time of their lives at the revamped Casa Bonita. Kyle’s group will see Kevin Stoley being the odd one out, as his sci-fi obsession irritates the group. In turn, Kyle and Token pick on Stoley for his obsession. Despite this, they have good times too, enjoying a fun VIP trip to the Denver Aquarium hosted by Token’s parents.
Stan’s group sees Bradley return from Planet Kokujon to resume life as a civilian. Bradley’s liked by all three other group members. Scott and Craig on the other hand, bring issues to the gang, with Scott being a complete bore and Craig bringing negativity with his increasing cynicism. Because of this, Stan and Craig tend to bicker at each other every 15 minutes.
The boys’ feud, though, will NOT be resolved by the end of the movie, and it gets carried on to the next.
