IS niyonica doing this...

Guys there are lots of theory for manek's and cabir's absense...I sometimes think that if manbir were saved and manek realised niyonica did this and confronted Her.,.then niyonica kept him underground...(remember during soha case she kept him underground)...or maybe cabir is dead and manek got pissed at niyonica and niyonica blackmailed him she will do it again to nandini so manrk went to Pune without telling anyone
