Iam not seeing any redemption track for sherlin as they did not show any remorse for her actions.and prithvi also not given her any shock which she thinks that whatever she has done for prithvi is wrong .and prithvi just used her .it was not the case .prithvi always used her but their stupid fights doesnot make sense.
Now coming to her mom illness and all they didnot shot for any hospital scene .and i think they will not shoot too.they just made her disapear so that when prithvi willl get exposed she will not be there and rishabh will understand she is also there with priyhvi in his past crimes .so when rishabh will tell her just divorce amicably .i will not tell anyone.then she will play her mothers card that she is ill or she cannot be given any stress and all as she wanted to live in luthra house but her aim will be changed .as of now her aim is taking revenge.but now she let it go .and asked a chance from rishabh by lieing.rishabh has not given her any chance we know about it.she had misconception that rishabh given her a chance by eating food.
So now her aim will be to stick around rishabh .that evil smile and evil background music when she sees rishabh photo and lieing to rishabh and all hint towards that she wants rishabh at any cost.so she will play these mom illness card so that she can stick around rishabh and writers isse kuch acha toh soch nhi sakte hai.
And then when rishabh will not care for her or anything she will be against preeta that due to preeta all these has happened .so she will behind her that you destroyed my life now i will destroy yours . So these is basically they gonna do with her.
