Roshni getting married to somebody else will mean the show can start to prepare on loosing ALOT of fans/viewers, so I don't think cvs will even think about that. So option 1 impossible (at least that's what SidNi fans hope for). 😆
Option 2 is highly possible since the cvs are in full on repeat mode. 😛
As per your imagination (3rd option), we will finally get to see a hopeless Sid feeling completely lost and lifeless due to the things happened to him rather than a hero and ideal 'James Bond types' Jamai. This will be something fresh and we can get to see more of Nia's talent in the new avatar. 😉 Love your imagination Rose, maybe u can tweet the cvs abt it.
I still have a feeling we might not get mandap drama. People have been disappointed in this track and the production house always considers fans feedback, so they might have understood that we are fed up with this repeating track and come up with something totally unexpected. I know I'm being an optimist here because I know the show overall has tremendous potential.. If only the cvs make use of it. 😕
