You were in Duncan’s group, they had gotten into a argument and Duncan had forced you to leave him. You didn’t want too.

Later that night after everyone had gathered food, you decided to go look for him,risking your life. You walked through the timid forest, hearing a hum from the lake, it sounded like Noah.

You find him there, a knife in his shoulder and rope burns around his neck. He was dead, how was he humming? ”You came back for me? Why?” He says, not bothering to look at you.
