Tupac is one of Caspar’s friends and was on the bus when it crashed.
Crash off a cliff
Mr. Edwards is badly hurt in the crash, but the kids all escape the with minor damage. That night, they set up camp, start a fire, and choose a leader, which ends up being Monty.
Searching for refuge
When Monty loses control of the group, they follow Caspar's lead and scale the cliff back to the road, where they find scattered pieces of a fallen satellite. Monty tries to stop them from going home, but the group follows behind Caspar.
The group find an abandoned food truck on the road with snacks and drinks in the back. However, Tupac decides to stay at the truck when the group splits in half and Caspar leads the other half home.
