I think This is the right time for Tand D to get back to blf track.
The engagement has been thwarted. Armaan confused with another miss understanding. Jassi should concentrate on her career. Now that GM belongs to her she should get back to work there as chairman and the story should get back to Betty and Armando scenes of BLF where both of them work face to face with both holding power.
Jassi brings back GM on profit making track.
Jassi and armaan realising that despite their misunderstandings andall those intruders (CJ) diverting their interest they just cant do without each other.
That famous scene Armaan reading jassi's diary(Armaan has not read it so far)only to realise that she loves only and only him.
ARmaan handing over the company to Jassi and deciding to walk out of GM so that she can concentrate.
Jassi trying to stop him and in turn offering to leave etc
Jassi learning finally how genuine Armaan is and hopelessly she depends on him emotionally. That Nut CJ realising that he is putting a futile effort
Suri's realising that ingredient of GM is JASSI and ARMAAN and they will have to be together for its functioning etc.
They decide to marry once again. Jassi promising the Suris that she will be a life and business partner to their son.
And finally their simple marriage and please end the serial with that.
