She did not take Twinkle's name so
What if, those clothes belongs to Leela-RT's elder daughter & Twinkle's OWN Sister (The person who calls RT)
Just like Leela is hiding about RT from Twinkle may be RT also hiding about Leela from their elder daughter
Well we know CVs loves surprising/shocking us, so when we all are predicting the caller as RT's wife or Twinkle's half sister MAY BE she is actually Twinkle's own sister..
Leela is a very strong lady I don't think the caller is her soutan or souteli beti...
Remember her expressions when she hugged Maya? & when she was angry on RT still looking at those old pictures lovingly, and the pic which Anita took there was a girl with RT-Leela, Anita recognized Leela from that spoiled pic but she could not recognize the child n RT, RT i understand but Anita failing to spot Twinkle this is something weird, what if that Kid with Leela-RT was not Twinkle but her elder sister?
Am i making any sense?
And what if Yuvi ends up Marrying Twinkle's sister instead of Kunj's sister?
