Basically, Jesse might be sent back. In fact, Jesse's mother discovered a long time ago that Jesse had seen aliens. Aliens have been aiming at Jesse for a long time, but Jesse has been fighting silently. In my memory, my son is very strong. At first, I bought a house and said that my eldest son had asthma, which also confirmed that Jesse was a very strong person. The old man said that there were still children sent back, and the aliens found it difficult and might transfer other targets. Three months later, the intercom rang again at the end of the film, indicating that Jesse was far away from them.
