Do you think that Karim and Janai will reconcile in s7?
What a good question! And something I've thought a bit about because of a fic I'm planning (in which Karim does not reconcile with Janai, but he loses hope after the battle and that has other results).
On the one hand, Karim was ready to kill Janai, he even told Kim'Dael to do it. That feels really hard to come back from for their relationship. It also proves that Karim really does think that there's no other way to save their people than eliminating his sister once and for all.
In the beginning he acts as though he doesn't want to turn against Janai, and he tries to let her live. But he steadily becomes more and more desperate until he's willing to kill his own sister. And for what? His people's future.
Karim might continue to say that he's doing it for his people, but I think that that's an excuse. He's afraid of change.
Of the uncertainty of his future.
I would have said; "No, he and Janai will not reconcile. He tried to have her killed, and then she went out and demolished his army without remorse. And rightfully so." But then... we get this line.
He was caught off guard, but I think his answer is true. I do think that he still loves his sister, on some level.
All of this is to say, I'm not sure. On the one hand, he could mirror Viren's political path and be "humbled and brought low" and that could show him how wrong he was. Or he could stand by his actions. At the time of my writing this, I am leaning towards it will be complicated.
In some ways, I think it would be even harder to have Karim change realistically than Viren. And that's because of one simple thing;
Karim hates humans, even after his sister falls in love with one.
But when Claudia falls for an elf, Viren holds no grudges against him.
This shows their priorities. Viren prioritizes family (admittedly often in a very twisted way) and Karim prioritizes tradition, even over his own family.
I could see Karim trying, but I doubt he will have a full reconciliation with Janai. He may be sorry, but I think he will be sorry for the wrong reasons. He may try to reach out to her, but I think she has every reason to not want to forgive him.
