You kill her and go to Carly next
From Create Your Own Story
After your nice drink you tell Sam that all that matters was that you were satisfied. Sam gives a confused look. You reach for your pocket and whip out a pocket knife. "Freddy! What are you doing?" Sam replies worriedly. You completely ignore her comment and slice her neck, piercing the jugular vein. Sam lies there bleeding out. You place the knife in Sam's hand to make it look like a suicide case.
