Maybe at first Priya hides that the SSP molested her. When Aditya finds out I think Aditya may realise what a monster his father is and try and fight to get Justice for Priya. This may lead to a drift in the family. Risabh and Gaurav who seem to know what the SSP is really like may help Aditya whereas Devyani will probably try and convince Aditya not to bring this issue out into the open. Devyani may at some point realise that Aditya is right and may have to cross her Maryada to help her son and punish her husband for his betrayal and wrongdoing.
This may be where the Lies, Deceit and Betrayal come in. Devyani may hide from her husband that she is helping Aditya. Uttara also seems to be involved in this SSP drama somehow but I don't know how she fits into this picture.
