Had Sydney survived Season 5, what do you think would have been her story-lines for the last two seasons?
I think she and Craig wouldn't have lasted while we'd see Sydney climbing up in the business ladder. Her untouched potential finally being put to use and I suspect she and Amanda would have been rivals.
I also believe she and Billy might have hooked up and I don't believe she'd stay to the end. I often think Jennifer got Sydney's sloppy seconds.
