The joy of stories in serialised fiction format is being able to witness character growth in an incremental fashion. Without characters undertaking a learning journey they'd remain caricatures, stagnant and one-dimensional.
Uma Shankar
I am genuinely intrigued to see how Uma Shankar learns to be accountable for his actions by confronting real-world consequences. The current Uma Shankar does not feel accountable to anyone but his dharam - however since he is the one interpreting the dharam it means he's actually not accountable to anyone...! And that's a scary thought.
Yes Uma Shankar has a moral compass but it's a really skewed one and even worse he has no idea it's skewed. If he keeps blindly following that compass with the conviction that it is taking him to heaven, and if he is leading everyone else in his family down that same direction too, then one day there's a real possibility all of them may end up falling off a cliff instead!
Kanak
And that's where Kanak comes in. She is someone who feels very accountable about everything because she has lead a life where she has been blamed for her parents death by the one woman she wants love from - Bhabho. Even if Kanak knows she is not to blame on a rational level, it's possible that deep down she may have internalised that message. And hence she grows emotionally attached to people easily (Shiv, Uma's mother), displays empathy to even those who are acting against her (Payal), and when she feels guilty she goes to all sorts of crazy lengths to atone for it (alcohol prank leading to a prayschit that she herself knew was over-the-top but resolved to do nonetheless). So she sometimes takes accountability very seriously - which means she also holds Uma Shankar to those standards and that's why he keeps failing in her eyes.
Kanak too has a moral compass. And we are better able to identify with her moral compass because it's been manufactured in the modern world. Kanak has the ability to lead people, just like Uma Shankar does. It's just that right now none of the Toshniwals want to follow her there - she wants to tell them that menstural cycle is not taboo, a woman has every right to go wherever she pleases without an escort, a woman can fly planes and save the world, a doctor should treat all patients male and female equally etc. That's the direction the Toshniwals need to be steered in so they can progress rather than fall off a cliff. However Kanak needs to build the skillset that convinces them that they should follow her to that utopia rather than continue eking an existence in the stone age.
Road Ahead
So yeah we have someone who has no sense of real-world accountability and someone else who will overdo her accountability and possibly take on guilt to an extent greater than her original errors. Both people value relationships - but one holds those relationships to conditions and uses vague divine signs to figure out what to do (forced marriage), and the other has no conditions at all when it comes to the lengths she will to for her relationships (undertaking deception to gain back a loved one's treasure). One has to change his nature and the other has to learn how to do the right things she does in a manner that is effective without over-committing resources to the point of exhaustion.
That's how I envision their journeys going so far.
