Not going to happen. Sadly. Seems like the Dadi does call her up everyday and is quite fine with her staying there despite the things she suspects.
The stage is set and none of the players are going to leave. In the end ig Radha (and her dadi and father too) will be left wondering 'how did it happen?' but she'll have only one answer 'this is what Baake Bihari wants'... else there was no way a poor, innocent girl who wanted nothing more than bringing happiness to her udaas Mohanji will end up getting married to him.
Only thing to be seen is who does what. The ghost more active and Gungun asking the right questions to Mohan are positives to begin with.
