I knew it....i always said that the person after jai's life would either be masi or aditya.....masi wud not be a good idea as there has to be someone left who is like a mother to jai.....so the only option left is aditya......he is jai's best frd, college frd, oldest frd, closest frd after masi, he knows jai in and out as a person, he knows jai's business and most of all he would be the first person who would want jai's money and empire.
Infact i wont be surprised if ranveer is in this with aditya....while jigyasa is oblivious to this.....and whne jigyasa does find out abt this she will hate her husband and son even more and will leave them and start being good to bani
Roshini, jigyasa, ranveer and ranvijay are too obvious.....plus they are very open abt their feelings and hatred.
So it had to be someone (as always does happen in all Ekta Kapoor serials) who is very close to jai and who would be the last suspect.
