They may have been aware of the theoretical possibility, but that's quite different from being presented with an actual threat.
Olivia is a long time lost, and until now unknown daughter. She's granted a Z3 rank right from the start, and put on the best position to show how she would lead the company ; even if the Board can overpass her decision, the Warden decide how the slaves are treated and how the VIPs are received.
There's no way that it happened right now just for the pleasure to reunite the family. And everyone in the Board is smart enough to understand this ; else they wouldn't be on the board.
Has the leak really protected her? Or has it made her a target instead? We'll see in the next ep.
What the intent is, and what the result will be are two different things.
But it's clear that, "hey the best male candidate is the half brother of the new female candidate", come like a benediction for the other daughters. The goal of the Gambit is to have the perfect grandson, and everyone know that an incestuous inbreeding can lead to the exact opposite result. This would compromise the Gambit, something that the Board wouldn't permit.
Of course, the male winner can be someone else than Kane, what would put Olivia back in the race. But she would then be far behind the others, supposedly too far to win.
You've forgotten Yvette who always backs her daughter Veronica's decisions, and the mysterious Gambit Queen who is very probably the 7th as yet undisclosed Karlsson board member.
I haven't forgot them. It's just that Yvette don't know who Olivia's mother is. Otherwise Veronica wouldn't have talked by innuendo, when she warned Elena to not interfere in favor of her daughter. After being so direct during all the discussion, it would be ridiculous to suddenly be subtle if anyone in the room knew what this part was about.
As for the Gambit Queen, we only assume that she's the 7th member, and your own assumption even make her unlikely to be it (see below). So far only Veronica's mother is a member of the board, while Elena isn't supposed to be the mother of a daughter. Therefore, the last member can be anyone else.
Dominique is the character who has expressed the greatest concern.
She's the one who offered a distraction to her main rival, it's not the same.
While Juliette will focus on Olivia, fueled by her hate for Veronica, she'll not try to counter Dominique's attempts. And in this play, Juliette is the one that have the most to loose, not Olivia. It's Juliette that might go too far, what would raise Veronica's wrath, whatever if she succeed or not, since Olivia is her favorite. This while Olivia wouldn't risk to goes aggressively against one of the four daughters until her own position is assured ; unlike Juliette, she isn't a member of the Board, therefore she know from start that it wouldn't end well.
Add to this an important point, the way she pointed to Olivia. Dominique is not as smart as Veronica, but she's smart enough to explain why Olivia is a threat for Juliette. Instead, she used Veronica, knowing perfectly how she'll react. Juliette hate Veronica so much, that she's now blind to anything else ; hell, she even forgot about her building orgasm ! It's clearly Juliette that have been removed from the Gambit here, not Olivia.
But anyway Dominique wouldn't care to have another rival, as long as it's a fair game. But it's not, and this is Dominique greatest concern ; not Olivia, but what she is, Veronica's favorite. Simply because it remove all fairness in the Gambit.
In the end, with a single visit to her sister, Dominique solved three problems.
Juliette will focus on Olivia instead of plotting against her, and she'll doing it fueled by her hate, so without caution. This while Veronica will focus on Olivia, in order to protect her from Juliette, and so be less attentive to Dominique ; what put back some balance to the Gambit.
As for Olivia, she'll be in the middle of a viper nest, to busy to really care about something else. Bonus point, Juliette being really extreme, there's chance that it disgust Olivia as much as it disgust Dominique. What could lead Olivia to decide that teaming with Dominique is the best way to stop Juliette.
I think all 4 of the original Karlsson sisters have very flexibile morality to the point that Juliette, Allesandra and Veronica have very little if any morals, while Dominique's are heavily compromised by the need not to look weak in the Karlsson shark tank where the weak are eaten.
Are you sure ?
Dominique have a high morality level. Of course, she's ready to pay the price if it's needed, but she'll always consider all options prior to this. As Kwame said, he wouldn't had survived if his life was in the hands of any other one of the daughters. She choose the human solution, where the others would have chosen the practical one.
Then come Alessandra, who's a switch in terms of morality. A nice girl who dream of a lovely family, what would have put her above Dominique in term of morality if she haven't been corrupted by the cold heart of her father. She see herself as the softest in the family, but also feel totally unfit in it, what make her give to some sadism, in order to not feel excluded. Like she said, unlike Dominique she like some noise when being serviced, but unlike what Veronica or Juliette would have done, she didn't made Kane be the one suffering. She appreciate the suffering, but if would have been cruel to make the one servicing her also be the one who suffer ; at least when it's possible to do otherwise.
After that come Veronica, that is the most neutral person in the room. It get what it get to reach an objective ; the end justify the means, period. If it's better to do it without harm, it will be. But if it need to walk on some corpse, she'll not hesitate a single second.
And finally come Juliette, the most selfish evil queen. Her desire come first, anything else doesn't matter. And she'll always give the priority to the most cruel way to achieve her goals. As Dominique said, it's surprising that one of her slave survived one whole year. Do as it please her, or die, there's no in between with her.
In the latest update, the Karlsson daughter who walked with the Gambit Queen
It's another possibility, effectively. The motherly relation would then be rhetorical, Kiyomi wouldn't be spying, and the description also fit her. It would also explain the interest that the Gambit Queen have for Olivia, Kane and Seth. But then that would imply that the Gambit Queen isn't part of the Board. Of course, she's would then be a founder member of the Karlsson Group, but keeping her seat after what she did would be strange.
Plus, as a member of the Board, she would have had more money.
That she don't used it to raise her children, I'm ok with it. It's by having lived this youth, that Olivia is now the best fit for the leading seat ; unlike the four daughters who always lived at the top and so built less empathy. But letting Seth in his state without using of her position feel cruel, the total opposite of Callista.
It also don't fit the "her" everyone use while, apparently, referring to the last member.
They (almost) all have a high opinion of Callista, why would they also fear her ? This especially apply to the meeting between Veronica, Elena and Yvette, where they (relatively speaking) longly praised Callista, but don't want to talk about "her".
Alessandra has invested time into developing Olivia as a sister/friend. She won't abandon that investment and turn on Olivia as long as she thinks she can convince Olivia to go along with her goals, whatever they may be. And that places her in a similar position to Juliette, except Alessandra's investment is greater, and her goals are less clear.
Reason why she fit more the point above. But as I said, your point of view is also a valid one, and is more backed up by the story.
Yep. Definitely. My suspicion is that Callista was hoping that together they'd use the powerful organization that Alexander Karlsson built to make the world a better place.
Or, said otherwise, they would effectively pursue Alexander's dream ; the one Callista and him shared before he died for the first time, not physically, but "psychologically". It's even possible that Alexander himself was an active part of this scheme. While it wasn't enough to, hmm, "save his soul", Callista defection could have been enough to make him understand that himself can't pursue it, and that he have to pass this dream to the next generation.
