Why I think today's turn of events hv potential for future strong storyline is because

• Arjun has comne out of love sick puppy mode and is back in revenge mode and this time with full vengence -Check
• Arjun has certain weakness for Geet which is good for future track-Check
• Precap clearly suggests dream wedding will come from tomorrow..they dragged it because as per hindu rituals during the period of sakranti ,weddings r considered ashubh..even though its a daily soap many PHs believe in all this..now the sankaranti period is over ..so marriage coming tomorrow-Check
• Brij part is not over and we will hv Brij-MSK confrontation during the wedding as per the promo but Brij will not die..becuase as per the old article one villain will pay the price and that villain has already paid the price by going in coma..which means Brij will stay alive and might maximum go to jail only to return back later with the help of Arjun..why Arjun-Brij will come together is because Brij will fail in his mission to kill Geet and then Arjun can take him in his side for further revenge-Check 
• NT has not died which means she too can b back in the future to add more masala-Check..
• Marriage is happening and MSK might go to jail for few hours but will b bailed out because he has not murdered anyone and Geet was a eye-witness of the whole incident which took place in the terrace-Check
• Geet gets half justice with the help of Almighty since NT goes in coma..her full justice will b over if Dev dies on the wedding day -Check

For me today's episode worked because of above reasons as it  lays a strong foundation for future storyline post-marriage...yes logically if a person falls from first floor,he/she doesn't go in coma but then this is not the first time we r witnessing such things in a daily soap ..so lets learn to deal with these issues...

Anu - I don't think any of us have any clue about GC's plans..he has yet to update his blog.....so we have no idea.....as of now..
