You decide that it would be best if you were the one to put them out of their misery, you lift up your weapon and pull the trigger.Sydney falls to the floor with tears in her eyes, you begin to comfort her as she puts her face into your arm. Afterwards she cries while you comfort her while heading back to camp, you then make it back
You both head into the shelter and get to bed, you and Sydney both sleep together and in bed before falling asleep, you hug her.
The next day you wake up in bed alone and in a panic realize that Sydney ran off.
