" I… command… you….to stay "
It was the last thing Isiah said before he lost consciousness while he was talking to Jaffar asking him to stay with him in that scary place .
Jaffar knew that staying here would be very energy consuming and that Isiah was going to die at this rate .
Jaffar started to dig a home under Isiah's body removing all the sand underneath him , then he stood there making him on his back then started to move .
He was not going to leave him behind alone when he precisely asked him not to .
Then he went back on his way trying to find Eeijar, he didn't know where to find her or whether she was okay or not but he did it anyway.
She was hiding too much information from him, she did it after the abandonment she encountered by Lucas but that was jeopardizing their own lives in return .
