if u remember vishal interview,he said that he is going to kill peole and people going to hate him.
then in another interview he rather funnily speaks about he wants to elope with paro and wants to marry her.i don't know whether it is a clue or not if it is then it is clear that myhra is paro.
shantanu may not be his name because he may killed someone and disguised himself as shanatnu.
after a year or so he escape from jail and kills paro.so he takes his time and made cunning plan to seperate rudra nd paro.
as he is psychotic person ,he loves to torture people than kills them.his main target is rudra and he wants give rudra the pain of loosing someone and that is what he is going through right now with his son.
he may have some obsession for paro so he didn't want to kill her but may have she injured and she got shot on her stomach part and there is greater chance for survival and if she hit over head there is chance for memory loss.
if he pre planned the shoot out then he may not got shoot by rudra and he take bullet proof cloths and he wants to make rudra believe that he and paro died.
in the hospital may be the real twist happend and he may come across with myhra with some accident or something .he make use of that situation and may have killed myhra and make paro in the place.
if myhra parents came he may introduces himself as myhra friend and myhra parents believes it.
as paro lost her memory when she regain her conscious and myhra died so no body is going to suspect him.
myhra parents take her to us and give her treatment and during the process the doctors giving her treatment thinking that she is myhra.
so after treatment she thought herself as myhra and we actually see contradictions in her as deep inside her she is paro but she can't recognise it.
if her marriage is fixed with shantanu it is also his part of plan and make rudra meet myhra to give rudra more pain and may be his dream getting married to myhra/paro in front of rudra.
if rudra able to see him once then he realises something wrong and tries to find out the truth.
it may be difficult for him to myhra that she is actually his paro but at last he wins and we get our jodi back.
this is my dream of rr in the coming episodes.
