OK, things are going so fast in this show!!
Didn't their dad show the photo of Sarla ma? So I thought Preeta and Srishti know that Sarla ma is their mother when Abhi brought them. Or does only Preeta know?
Srishti was mad at Sarla ma and cursed her when Sarla tore Tanu photos. So it looked like she didn't know she's their mom.
Did I miss something?
