Concept 41 #3:

In the film I want to write my characters’ point of no return is when they have to conquer their fears and explore the new world they have discovered. When one of the protagonists get sucked into the new world, the other one has to be courageous and jump in after them. If they didn’t then they would be forever separated, and they would risk never seeing each other ever again. The families and their friends would never see them again, because if they separated they would have a low chance of surviving and returning back home.
