I had a theory long back what if anu and bajaj were not in this together...
I always felt what if divers kept by anu were different and bajaj bribed them and took their position... maybe what bajaj said about someone informing him was true... as anu's dialogue hinted today that bajaj had eyes on other's things... which in this case is pre...
Those divers were supposed to save pre ... but anu kind of anticipated pre's move as he told her he will be at the farm house later... he knew pre will come to confront him so he was ready with the act... what he didn't know that bajaj was with pre... when pre came to confront anu... bajaj closed her mouth and took her away...
Anu hoped pre will get upset and run to basu house to take their kid away and learn sneha is at the orphanage... thereby killing all the hopes pre would have ... what he didn't know that bajaj would take pre to the orphanage...
Maybe anu learnt later that bajaj took pre to London when he came to check on pre at sharma nivas.... and realised she was not there... so he found out about it... but he left it as for him that time pre's safety mattered more...
My theory also included bajaj went to the orphanage first and bribed / blackmailed chandrika... meanwhile he was ready in the water to save pre.... he created a fire scenario which led to pre believing sneha is dead... also the same guy (maybe he is that bajaj's informant) informed that both chandrika and sneha are dead to komo... when anu checked with chandrika ... she informed him that pre took sneha away....
But seeing how the makers are changing stories overnight.. seems everything will be phuski.... only thing good in today's episode was pre has started thinking.... hope she realises the truth soon....
