It makes sense, but it's still pretty early (in my opinion) for such a scenario.. Oh, and Olivia is still Z3, she's not a Board member yet and will only be able to join when she proves that she has successfully completed the main task assigned to her (Prisoner Reeducation Program).
I think key things like internal wars, actual assassination attempts, etc. will start happening when we're given the opportunity to finally choose the factions we're interested in (which, as I understand it, won't happen until pt 2-3 of ep8). And given that ep8 is devoted almost entirely to violent game show, I'm guessing that the internecine wars between the Karlssons, DeKocks, and other interested parties won't start until episode 9 at the earliest.
The game show will not be spoiled by internal strife, on the contrary, it is important for the Karlssons to demonstrate to all factions (VIPs) that the Karlsson corporation is strong and powerful, no matter what.And if during such a demonstration of their greatness the lion bites off one of its own paws (sisters), it will look like weakness and disaster, which they cannot allow.
