Our "simple Jack" Kane couldn't even figure out she was Stacey, what chance does he have to understand her work?
That's not true. It's exactly the opposite.
As for the intellectual connection between Vi and Kane, I was primarily talking about the deeper level of the relationship that has been building up since their childhood. As I've written more than once, it's a long journey, and freeing Veronica by taking her out of her usual Ice Queen shell won't be easy.
So for lovers of the here-and-now, surely someone other than Vi would be more suitable. Brave Angelica, schemer Alessandra, sociopathic Juls, hesitant Dominique, etc. My saves include romances with lots of chars, incl the Alessa+Celeste+Kane(Dom) arc, a romance with Dominique (Good & Evil), a relationship with Angelica, and even a "romantic" rs with Jules...But that doesn't mean I don't love challenges and hardships. And it was my Kane's (Dom's) romance with Veronica that was the challenge and test that I consciously accepted...
Besides, I just like her. She may not have the flamboyant beauty that some of the other sisters have, but she (to me) has her own special charm.
As for Vi's science work and Kane's abilities, first of all, our Kane hasn't had much practice in science work yet (but we have everything ahead of us, especially those who accepted Vi and Dominique's proposal)...But even as an intern in Veronica's department, KaneDom was showing good results. So, as they say, give it some time and this guy will still show his best.
