Yeah but doesn't he complain to Stacy that he has to learn so much? And If Alexander wanted Kane to be strong and a worthy father to His true heir, then I see no readon why callista would not try to educate him well. She also wants him to win the gambit and a highly capable Kane would have better chances. And Olivia got a private teacher while being with Callista too.
Kane was a blatant reminder of Alexander's failures. Because Alexander failed to remain faithful to Callista, he lost her. Kane's father is Alexander's best friend (big loss). Callista ran away to escape from Alexander so, other than being the male carrier of Callista's bloodline and a means to offer leverage over Cole and Callista, I don't think Alexander cared a damn about Kane. Just my opinion.
I'm thinking part of the reason we don't see him excelling is because he hasn't been in a position to shine yet and maybe doesn't realize what his capabilities truly are; confidence goes a long way for a guy when he has it. I could be way off here but I believe he's really a diamond in the rough. The other thing we haven't seen yet is his leadership ability. That's a skill set all it's own and he hasn't had real chances yet to develop or display that.
Maybe it's just me but I keep thinking the reason Kane was kept in the dark about so much (frustrating as it is) was so he could be tested in the gambit. He no-kidding has to prove his mettle for the Karlssons to accept him later and he has to be seen as "earning" his position vs. inheriting it as Olivia did (remember: this is matriarchy and men are 2d class citizens here). Everyone is watching him and many are looking for clues that he's been getting unfair help; I think if he knew too much walking in to this it would show. That's part of where the whole "bomb" theory comes from.
He did get an education (he complains as a child about all the extra homework Callista gives him) and he is shown to be quite bright in his own ways (look at how he inspires Veronica the Genius with the things he says to her) and the Karlssons recognize this--depending upon your route and choices, they introduced him to some projects they aren't even sharing with other sister/board members. Finally, she taught him character and ethics (again, your choices decide this). You only have to look at the other Karlssons, et. al to see what a difference character and ethics make.
Is Kane maybe also aware of everything and also just plays a role? Maybe even he and Olivia are actually working together behind the scenes (I know this sounds kinda far fetched, but I just looking for reasons why Kane isn't on the same level as the rest of his family)?
Really interesting thought. I'd never considered that. It would be a crazy plot twist if the dev pulled that off. I'm not sure that happened here, though, because of the scenes where Olivia pulls Kane into areas that seem private to tell him things (like who is father is, etc.) and it seems several times in the game where they appear to be alone and not monitored that she is trying to see what he thinks and to gauge who he is/how much she can trust him. If they were in cahoots w/ each other, I'd expect she already understood these things. But great theory; really.
