hey i think maybe abir will turn karan part 2 u know like karan was bad guy before because of mandira n later gets to know how she used him n all ...same way abir too cud get to know tht raj bhasin is perhaps not his dad ( if he's age of tulsi then he wud be too old to have a son of abir's age ) or maybe abir doesnt know the whole story of raaj bhasin like wat he did to kesar n y tulsi is against him ....and honestly if abir needs to change bhoomi as his wife wud only make him a dracula so archita wud be gud for him maybe he realizes wat love is thanx to archu .( i cant believe she's mohini's daughter ). and just like karan taught damini to respect her marriage with gautam ( damini was karan's ex gf ) same way abir too may teach bhoomi to respect her husband joydeep.
and just like even though all were aginst tulsi - karans tood by her side like a strong pillar ....abir too cud be same atleast the guy has guts n doesnt change colors ( his intentions be it gud or bad r clear) and not a backboneless person like eklavya,lakshya, KT , tanya damini ( these characs really need the boot of their lives for having forgotten all the good tulsi did for them n actually targeting her )
all in all - history cud very well repeat itself
PS- WUD LOVE TO SEE TULSI GIVE THEM THE KICK
