sanjam dies after that............well......they don't show this scene as it actually happened.......because that would be inappropriate for tv.......
but this is what happened in actuality:
Prithvi and Sanjam were both heavily injured as shown in the show. Next, as shown in the show, vultures surrounded them, Prithvi was unconscious, and Sanjam was too injured to kill them. The vultures were all coming towards Prithvi, cause they thought he was dead. To save Prithvi, Sanjam cut off a piece of himself (I believe his finger), and threw it at the vultures.
As the vultures finished one part of him, they would try to eat prithvi again, so sanjam kept cutting off random body parts, and threw them at the vultures. He basically partitioned his entire body for them, so that they wouldn't kill prithvi.....cuz vultures naturally eat the person who is "more dead" first........
In the end, the vultures ate almost all of sanjam......When Chander, Sikandar, and everyone else discovered him, only his head was there.....the rest had been eaten by the vultures......because vultures only eat the body.....they don't find the head appealing to their appetite.......
If you notice, when they do Sanjam's funeral, and what not, they only show his head.......they don't show any other part.....That was because, in actuality, these parts didn't exist.....
That's why Sagars only show his head after the cutting scene........
