RED Part 1

Y/N has been hunting since she was 18. She's seen and faced things that nightmares are made of, but when she hunts a Demon that turns out to be none other than Dean Winchester, the man who saved her 10 years ago, things take a slight turn and she finds herself, caught between doing her job and killing the man that had stole her heart many years ago. Will she be able to save him or will she cross that line into the blood red world of his?
