Confused with characters

Who is Durga to Payal? In the 1st episode I think it was said by someone that she's doing so much for a stranger, but then people are saying she's Payal's sister. If she is Payal's sister was she not there when the whole thing happened 2 yrs ago?
Is Payal the daughter of the Goenka's past driver? Does that mean Baba was the driver and how do they not recognise Baba as the driver then?

It hasn't been clearly said yet but it looks like as if Payal is durgas sister and Durga is hiding her identity from everyone to complete her mission; so she may be Paula's sister nitya. Yes she was there as seen in the fbs but maybe she done a surgery or something which changed her look. Yes Payals the daughter of goenkas driver as seen in the fbs and I don't think that's baba; it's not yet revealed where has her parents actually gone but dr Dayal is not her father I guess he is just taking care of Durga and helping her in the disguise of her father but I'm sure more of that will be said later

This is hell confusing. Yes in the first episode if I am not wrong she said that she just came to know that her name is Payal then how come she is her sister now ? First I thought as a good human being she wanted justice but now she gets FBs and her emotions are like she understands the pain that Payal is going through like she suffered from the same thing or like if Payal was someone really close to her. But if she is Payal's sister then who is Baba and how did she meet him and why is he helping her ? So many questions. Hope we will get the answers soon. But I seriously am against surgery and all the blablablah. Otherwise I better watch an EK's show then EHT lol. Plus I so love her and Baba's chemistry that I don't want it to be ruined.

The actor who plays her dad is handsome I must say but they both have different eye colour

Just wait and watch... The show will answer all yr questions soon

well she said in the first or second epi that she js knows that her name is payal...ohk..she said that...cox she doesnt wanna reveal this thing to nybody...nybody...that payal is her sis...cox otherwise Goenkas can get to know that Durga is nobody else but Payal's sis...who is here to take revenge...so she told that doc lie that Payal is stranger to her...
