Bidaai so far

I want to know who is Anmol and what happened with Ranbir. I was out of the country for a while so couldn't catch up with Bidaai. The last episodeI saw some dude nname KAran was blackmailing the Rajvanshs for Ragini and Sadhna's pictures. The other day I was switching the channels I saw an add ragini with kids and Anmol( apoorva). What happened to Sadhna and Alekh ? Can Someone update me please
Thanks
