Since 2 days i see Prerna sort of taken a stand and she is shown as praising Bajaj. She also goes to the extent of saying not like Anurag and she is not shown as missing him.
If this is the route she is going better take Sameedha, Basu City, and go back again to London with Bajaj than thinking abt revenge and stuff which anyway doesn't suit Erica and this show can be ended also.
This option is better than continuing with gol gol story.
