While Veer is planning a bride swap and Annika being forced to help, could there be a groom swap being planned in the background? As a result Ruvya will get married along with Saubby (Saumya + Chubby). This would justify Saumya's pic with MS and Chubby's sudden reappearance.
What I also noticed in the kitchen scene in today's episode where Annika is trying to hide Veer n Saumya, Shivay behaves in the usual loving n caring manner towards Annika when she acts that she is hurt. Veer didn't notice it? Isnt Shivay supposed to hate as he believes her to an imposter? Possibly he already knows n is only playing along to trick them and using Shivay as a bait to get things done from Annika. While Shivika have a counter plan with the groom swap as they alreay figured out that Veer knows Annika's truth.
Well just an intution
PS- BTW, none of the brothers got married in a normal, conventional way and the initial period post marriage was filled with hatred n fights and not one to start with love n care. So will Rudra's marriage be any different. Could Rumya be married n then they continue on the lines of Shakespeare's "Taming of a Shrew?
We should know soon ;-)
