One thing I have seen is all articles keep stating Anki as "Face of PR" and production house statements repeating the same,to me it says a lot.
Whatever conversation Ekta and Anki had ,I am sure it's for good for both of them.
So I am sure if Anki has taken this step to come back (rejecting a offer of lead from a popular production house for PV2) ,I believe its carefully consulted (With Sush ) and analyzed one.
I see 2 ways of Anki's come back :
1)Bringing back Archu from Coma,solve all props end the show and another new show with Ekta.
2)Bring back Archu from Coma,solve all props take a huge leap and Anki coming as a young character in the show,PR continues.
Not sure which direction it might take but one thing I can see is that Anki's decision does not look sudden but carefully considered and her n Sush's equation with Ekta is very well maintained which is a good sign.
