This reinforces my point that it's in BB's interests to let Vic the incumbent lose, something like Gunter beating Ron. Thereby making the Olympia more interesting while forcing Vic to go to a higher level and get truly cut for once, as well as to work more on the legs. He needs this kind of motivation, he's been unable to do it.
Kai doesn't have the long-term potential to win the Olympia, and satisfied Weider's general preference towards the best conditioned guy as the winner.
