I think they are gonna go ahead with their earlier plan where surbi will have a daughter and the maid will have a son but to save surbi's life they will exchange babies so surbi can have the boy and then obviously they will all love surbi's son more than lakshmi because he is a boy. Thats why they are creating jealousy in kajal's mind. Even now with samrat she feels threatened that no one is interested in her daughter anymore.
Yes mayb thats y they are creating her jealous... But i guess surbhi will have a boy but she will give his son to driver wife 😳
