OK, in a typical way to advance a serial with a nonexisting storyline forward (TRP mata ki jai ho), the makers bring in a leap or a new character. People even bring on a dead and buried character to life, with a possible plastic surgery.
Here is my prediction about Ghum.
The bus hangs by the cliff. Virat manages to save Sai, Savi and Vinu. But not PL.
PL falls off the cliff, and is presumed dead. Just the way Sai was.
V is broken once again. Seriously, what sort of emotion handling training did he undergo during his IPS days? Sai steps in, egged on by Ninash. Unka kaam yah hain.
Years later, this is a happy family. Savi as a police officer, and Vinu as a doctor. Vinu now harbours hatred against Sai and Virat (he has seen his mom fall off to her death because his baba preferred dr aunty). He grows up with vengence in his heart for Savi.
PL, who is not dead, reenters with a new face, thanks to plastic surgery. She manipulates him against Sai..
Carry on forward! Ghum season x?
Please add on...I am not tagging anybody.
