It's kind of understandable the way Megha is acting with Rimjhim, since she left her kid and decided to live with Sameer and his niece and nephews. Megha has always thought of Malini as her real mother and I don't think she will ever understand that in reality, Rimjhim is her real mother and when she does, she will be a teenager or in her 20's...so I can see where she doesn't really want to do things with Badi Maa Rimjhim...she is not the Badi Maa she is the only mom. Damn that Malini for screwing with Megha's mind.
By the way, why is Megha now 7 or 8 years old? In the past episodes she was 3 then she kept growing...so this means that Rimjhim has been going through all this for 5 years now and Avinash's marriage to Malini has been for about 6 years? WOW that is a huge gap that they are not telling us at all. They beter shring Megha's age to 4 at least.
