At the very end of The New Daughter, Sam faces a dark and ambiguous fate, strongly implying his transformation or demise at the hands of the mysterious creatures.
Sam is last seen outside the burning house, clutching a family photo, as he watches the chaotic events unfold. Following a significant explosion, a figure is visible in the reflection of glass, seemingly walking out of the flames. However, the more critical development for Sam is the appearance of three "mound walkers" stealthily approaching him from behind.
In his final, haunting moments, Sam utters a questioning "Daddy?", but his plea is met only with a chilling screech as a reply. This terrifying response, combined with the presence of the creatures, suggests that Sam either succumbs to them and becomes one of their kind, mirroring the fate that befell his sister, or is directly killed by them. The film concludes on this unsettling note, leaving his exact transformation or death unseen but heavily implied.
