I highly doubt that Sonu will be sent to boarding school, but if he is - here goes my far fetched prediction - Prishna will reason with Ganga and calm her down, by then TTS will be back, then Prishna will say that they will move to where Sonu's school is and live there, then Pintu will get a job to take care themselves while Krishna studies and takes care of the home, and then Pinky will be left all alone with no one to torture except Babloo and TTS.
Anyway, I was just having wishful thoughts which never come true, ... but yeah back to the show, ... I don't think Sonu will be sent away, TTS will come back in time with some crazy demand or maybe bring Pinky's parents to stop them etc. Pintu's job track won't happen just yet as well as Krishna's studying for IAS, as for Pinky's job - she seems to be the luckiest BDO who has no work or works from home.
