If she is acting good good .. even with kamla.. then.., Prem might also have to act good and be friendly to Kamla and her family... Including Kalpi.. so it is not just about Rakhi.. ( With Raghav...Rakhi is no tension... it would be brushed off easily and both RagNa can handle crazziness of Paakhi..)..
Real times of test will be with Prem starting with Friendly drama with kalpi.. and he develops feelings for Kalpi..(hope not real ones)... and This would be major blow..
Pakhi is crazy.. and Prem is in search of right way and time to give blow to both... Raghav and Kalpi... he is strong... Paakhi can be defeated..
RagNa will have tough time dealing with Prem..!!
