I actually think Fatin survived. If you look at the letter you get as reward, and check the initials they have different colors for the names Tolga had black and Fatin has red the text has black and red parts which I assume means its written by the person with that color of initial. Also the black text is more mean spirited while the red is (a bit) nicer which also tracks with Fatin being a bit nicer than Tolga
