I am seeing many comments that Abhinav didn’t understand jail thingy .
he understood it very well . He knew that he and Rubi went to jail because they are the target for no reason and because Abhi spoke against Eijaz but he couldn’t say this for obvious reasons . Because he couldn’t tell the real reason so his next option was to accept that his reasoning for jail was wrong so he got punished .
Because his reasoning was not wrong so he claimed he didn’t know why he went to jail , because he wanted BB team ( Salman ) to answer that but they couldn’t . Salman was fumbling and kept mentioning dand word . Dand mention nahin kiya.... Arre woh dand hi de rahe the with their reasoning . Salman couldn’t justify why they went to jail . And here Abhinav was successful how he made them look like a fool because they couldn’t come up with a proper justification .
