Yahi khayali pulao pucca rahi hun , aaj kal .
The Riddhima's mystery revelation hopefully be bombastic.
My theory :
Riddhima belongs to a mafia family , where she has seen only blood shed her entire life.
That's the reason she was sensitive towards the killings and tried to save ragini and didn't try to kill Kabir is because she might have seen people killing each other, people killing her family . She might have become sensitive towards killing or hurting people.
The other reason , she just left ragini , when she was dead .
Why she left ?
Because she is dead , she tried her best to save her when she was alive but when she is dead, she might have known there is no purpose of carrying her ,when there is just the body/corpse with her.
She might have seen many deaths , dead bodies around her and she is insensitive to the bodies , when you can't revive the dead body what's the purpose will it , leave you protecting the body (specially in mafia they don't care about dead bodies much , if you had any emergencies ) You don't take and keep the dead body for life right .
Riddhima's family definitely a mafia family .
She even can handle rifle so well , which she cannot learn and practice in mere 6 to 7 hours .
She doesn't even have a Kabir to make her do a crash course.
If you are thinking about vyom?
Vyom - he is double crossing her .So , definitely he couldn't make her learn anything about mafia in mere 4 to 5 hours , right ?
There could be none of them to make her learn , even if you take family possibilities .
If anyone in family are her partner, why would she suspect everyone ?
So , the possibility of her learning mafia rules ends with her family being mafia .
Now the question could be , why would she hide ?
She might be in a problem , may a life threat .
Riddhima's mafia family might be a BIG MAFIA FAMILY , they might be ruling india in mafia business .
They might have many rivals .
I even feel , Riddhima's dad might be in jail , which might made the whole families lives into death threat zone .
Suiting there environment , they might have taken the decision of hiding or keeping there identity low , all the family might have scattered to there own ways ( maybe because there might be pretty less people in the family ,like 4 members in a family)
Riddhima started living like a orphan doctor in the hostel and started to make a living .
She caught Kabir's attention and rest is history .
She might always wanted a family and she always wanted husband with a simple background .so ,she could live a peaceful life .
But fate brought her towards vansh and in the jungle sequences , she might have realised "she was born in a mafia family and she did end up in mafia family again ".
Now there are three reasons why Riddhima is doing this -
1. She might be trying to make vansh leave mafia .
2. She might be trying to protect him from vyom and her mafia dad , who is probably back from jail and doesn't want her to stay with vansh and family , because he finds them incapable .
3 . A big game going on and vyom is trying to make vansh, riddhima and her mafia dad fall apart , so she trying to protect them and save them from that game , if vyom has to win something then it has to Riddhima's dad , if he is the biggest mafia in india .
So , he might be playing a game to gain both the mafia powers by manipulating vansh , riddhima and Riddhima's mafia dad .
Now other question , why riddhima reacted the way she she reacted on parents accident ?
She might have reacted that way because , one of her parents might have been really dead because of that accident .
Her mother might be dead .
She might have been upset knowing that , vansh was the person who probably reason her mother died .
Later on , she just made peace with the fact and it's not like vansh killed her mother .
So , she was not really hurt .
Ps : it still feels like I am writing a story than a theory 
I have already posted many theories in one post associated with current track .
