I saw a warning at the top of the fic about a future main character death, so it put me on edge (or I may have imagined it)

No, you didn't imagine it. I put that on part one because I know some people don't want to get invested in a series if it's going to end badly. And this one - well, the whole thing begins with Sam's vision of John's suicide and that vision will play out by the time I get to the end. (Not exactly as Sam is seeing it, but...)

So the warning is real enough. But that will be the last story in the series, when I get there.

Enjoy!
