Irritated over Pavitra Rishta of recent

Now, to get to the point of this thread...I was honestly shocked when I viewed the last episode (I think we are a little behind here in New Zealand) but I was disappointed in seeing Archana believe everything she heard from Ajit about Manav and the entire storyline of the pimp etc. What really bugged me was that as his wife, she chose not to believe him and believe a lying decietful rat who we all know beforehand was caught trying to conspire against Archana (ie: the whole Vinod putting him away storyline). What I noticed though the most, and this certainly got me standing up is how the producers made a mistake. Rewind a few episodes back when Varsha overhears her sister in law's phone call to her mother and how they conspired the entire time all of this, then why did she not come to Manavs rescue and realize all that she heard on that day over the phone when Manav was telling and pleading with everyone that Ajit is indeed behind this entire conspiracy? Thats what really got me fuming. Well, at the end of the day it is just a show and no doubt those who do wicked will get a shock of reality when the actual truth comes out (Indian serials are always like that) but I just wanted to make that point. Why is Varsha not seen investigating more into the matter after what she overheard on that day her sisterinlaw was on the phone?
