10 MORE Worst Betrayals In Horror Movie History
5. Jamie To Tim & Millie - Together
In this 2025 body-horror, Millie and her emotionally distant fiancee, Tim, move house to start a new life. Their neighbour, Jamie, welcomes Millie with open arms, urging her to explore the walking trails nearby.
During their trek, Tim and Millie stumble upon a cave where they come into contact with a strange liquid. Soon after, a supernatural force begins drawing Tim and Millie together, to the point where their bodies attempt to fuse together.
Recognising the liquid is to blame, Tim ventures back to the cave, where he finds another couple exposed to the goo, who've since merged into a grotesque hybrid.
Adding to the horror, Millie discovers Jamie is part of a cult that uses the liquid to fuse couples together to "become whole". Jamie engineered events to ensure Tim and Mille consumed the liquid, forcing them into his ideology without their consent or knowledge.
Although Tim and Millie accept their fusion, it's only because fighting it will turn them into a monstrosity, like the one Tim saw in the cave. While Jamie believes his actions are driven by love, it's hard not to wonder how many people he befriended and betrayed to satisfy his agenda.
