The Prodigy Ending Explained (Spoilers)
Is A Sequel Possible
While Sarah is killed, when she tries to shoot Miles, his father is still alive, just in a coma for now. So between his foster parents discovering Edward has taken over Miles’ body, or his father awakening and finishing what Sarah started, a sequel could be made.
How The Movie Ends
We learn that, for most of the movie, Miles had long lost his battle with Edward and he was just masquerading as the kid to keep the peace. However, once it became clear that John and Sarah agreed that Miles needs to be put away, he tries to kill John. With that in mind, as a latch ditch effort to save Miles, Sarah follows Arthur’s advice in trying to help Edward fulfill his final wish, so maybe he’d move on.
Unfortunately, that would mean Sarah killing Margaret St. James, who survived Edward and is the reason he was shot to death. But, Sarah didn’t have it in her to shoot Margaret, but Edward did have the will to use Miles’ little body to gut her. Leaving her dead, but Edward still in Miles’ body. So, to stop him from killing again, and keeping Miles’ body, Sarah goes to shoot him but ends up shot by a farmer.
Thus leaving Miles, with his father in a medically induced coma, and mom dead, in foster care and looking at his foster mother’s wrist. Hinting that she could very well be his next victim.
