Larry?
When Cool asks if his dad is coming back and Grandpa says "no" are we to assume he's on the run for good or that he knows his life is over and will be killed?
The way the grandpa answered that was very dark sounding because even as selfish and shallow as Larry was, he still has his family and son there waiting for him.
Thoughts?
Eventually, all things merge into one, and a river runs through it.
