Spoilers for 305!!!
Personally, I wanna see the big bad as the "real" Max, who went to heaven thanks to his selfless act and, upon seeing that Sam has replaced him, goes into a freakout and enters an epic (player-controlled?) mode as he takes over heaven and sends various disasters his former friend's way. Of course, it will all be riddled with humor (Max: I die, and he just replaces me like some sort of goldfish? I'm gonna go on an online forum to complain about it and write a fix-fic about how it didn't happen!!), but still be pretty dark as Max sullenly forces Sam to make a choice.
Although if this does happen, my in-progress fic about this very scenario will be worthless.
