I don't know if anyone has posted this or not but here is what i guess would happen in JJKN.
the new guy (Karan Oberoi) and neha will become friends and one day neha realises that she is pregnant and karan gets to know about this, Neha will tell him the whole story and Karan will feel pity for her, and will propose her for marriage, explaining her that what people will think about her character and etc etc, how will she bring up her child alone, what name will she give. neha will tell ,my child will get the same name i got, I don't want anyone's favour or odn't want to be a burden on anyone blah blah blah... after listening to this karan may fall in love with her, ask her again for marriage, and that time Neha might say yes. Meanwhile Armaan will someway findout some clue on the nainital thing and go there for research, and after that is done ,he'll find out that Jassi is in nainital and wants to meet her, and when he will meet her that day jassi would marrying Karan....
wooz... That's all i think. You guys can out your views in.
