Like Vaughn said Oh felgercarb! :lol:
I thought for a moment that Sydney was the one missing or something like that, I didn't except it to be her father
I don't know what she has in mind but it can't be good, come on Vaughn do something and run after her! You can't let her ruin her life because of Jack
With two chapters left, I feel like she couldn't have killed him. And I think it'd be strange to have her torturing him... can't have the protagonist so harsh. Maybe she confronted him, he hurt her, and then he ran away...
