What if a beautiful lady joined Nathan and Sam Drake on their adventure to find Henry Avery's treasure? Delilah Hunter has been best friends with Elena Drake since they were in high school. When Delilah was looking for a job, Elena got Delilah a job working with Nathan. If it hadn't been for Nathan, Delilah and Sam would have never met and had a blossoming relationship.
(I do not own anything Uncharted related. I only own my character, Delilah Hunter.)
