I think it will be hard for Pratigya to win Krishna over so easily. He may decide to go to Angad's friends to find out the truth about what happened. Remember in an episode, Krishna and his friend went looking for them and whilst Angad's friends were hiding, they promised themselves that they wouldn't tell him about the kidnapping because they believe thats the reason why Angad was murdered? So they may lie to Krishna and cause another problem.
I also think that if Pratigya goes to the police about the Thakurs he may take their side. If Aman re-enters at this point it may further anger Krishna to see Pratigya and him working close together.
NOTE: I don't want any of this to happen but it would be too easy for Kriya to be together until they have overcome ALL their obstacles. It has taken this long for Pratigya to realise Krishna's love for her, so it may also take Krishna a long time too.
What do you think?
