Cv's biggest mistake in PR1 was that they rushed into Sher and Shardha's wedding.
In PR2 they will not repeat the same thing and will take their own time to blossom the relationship/love between Shamsher and Aradhya.
From what has happened so far, the story could go like this:
Veer could propose to Tilakraj for Aradhya's hand, BD seeing this would get alarmed as, Veer becoming Tilakraj's son in law could mean Tilkraj getting full police protection. BD to stop this could ask Sher to marry Aradhya, as she know Shamsher's interest in Aradhya is zero.
Or
Veer could tell Tilakraj, to get Aradhya marry Shamsher. This will bring Arjun and Shamsher apart.
Or
Aradhya falling for Shamsher...as opposites attract
