I agree that Sydney is realistically the most vulnerable at this point. Not only is his character pretty “used up” so to speak, but there might be scheduling issues with the actor. I honestly wouldn’t mind his death very much. I thought that he was pretty decent until the “Fruit of the Poisonous Tree” episode. After that, I just wanted to strangle him.
And I don’t want August to die. I’m starting to really like him.
