Aman had a fight on sets but chances are he stays put with new girl introduced into storyline. It's not going to be a one time gig for her. IG is needed for future story lines and clashes between SS and IG. There is no other storyline for SS other wise besides tryying to kill Prats and getting KN married. He has to clash with an outsider about his own lifestyle. The KN wedding will bring Mathurs into the picture for bigamy etc.. POPs have done a lot of research recently for Mathur storylines. I don't see the family as such going out of the picture.
The marriage proceeding makes the most sense. If Arushi calls off the wedding, she has no story line left other than another enoc**ter with KN, either way it leads to a dead end. What do Saxes have if A-A don't get married? This marriage is a catalyst which will blow a whole lot to smithereens. Aman the Ram is not a ek patni man but a man with a sweetie on the side. Gaurav asked him about his sacrifice and Aman was sweating bullets. It's an eye-opener for the Saxes that education doesn't automatically mean a stellar character.
The Saxesare the personification of padicha muttal (educated fools). The A-A marriage will cause a lot of drama in all three families.
Logically thinking..thats the plausible scenario but I fervently wish for what I had said ....I truly want Aman out !!
