All the potential of this story lies in the arc of Raghav falling first! That is the only reason why he was made to torture her so much yaar, so he can be the one suffering in love Kabhi to in life he needs to yearn and beg for something!
Pallu falling first, what plot will that achieve? Bas melodrama hoyega No no please... Ek baari to iss ladki ko upper hand milne do 😣
Raghav ke kismat mein sirf pining hi likha hai. Pehle Amma aur Keerti ko waapas paane ke liye, phir Pallavi ko. He needs to learn that he cannot control his destiny and that some things will always be out of his hands. That's where faith comes in and he has to learn to build on that. Only then will his ego and pride stop being a roadblock for him, warna uska kuch nahin ho sakta. 
Also, based on what I'm seeing of Amma, I doubt she has it in her to heal her son's wounds. Only Pallavi can do it. Though I am scared of his pyar mein mar mitna philosophy. Tab dekho kitne volcanic eruptions hote hain. 😕
