Plot hole: Brent discovers that Taylor is on the planet and has a connection to Nova through the dog tags she is wearing. However, throughout the first movie, Taylor never had any dog tags on his person. Also, his ship was destroyed, and he only managed to retrieve a life raft and supplies. His belongings and clothing were taken from him when he was apprehended by the apes. Taylor should never have had any dog tags to give to Nova or for Brent to discover. (00:11:10)
