Both Nima and Gerry have split-endings.
If Nima chooses the can, she dies.
If Gerry misses the jump, he dies.
If both die, Jesse goes off alone and is seen crying.
If Nima and Gerry live, it's a happy ending.
If Gerry lives, and Nima doesn't, Jesse is sad that Nima died.
If Gerry dies, and Nima lives, Jesse is sad that her dad died.
