I am justifying this yeah, and we don't see this regularly in real life but the fact is true that it is possible even if the chance is one in a billion. So let the lookalike thing slide and remember that there IS a possibility of it happening... just continue to enjoy the show. Tumhari Paakhi has been great about justifying things, showing logical tracks, and closing loopholes. Just like in today's episode where all our doubts about the Singapore track perfectly came to a close with the revelation that Rohan and Anuja were working together.
So all I have to say is to think positively and continue to enjoy the show - these shows are meant for entertainment purposes anyways, so continue to be entertained. And I think this will be a very light-hearted comedy track based on SBS!
By the way, who else thinks Paakhi might get pregnant soon?
