In the season where Sam undertakes the trials, he rescues a soul - Bobby — from hell, and Naomi flicks him to heaven. In the final season, Kevin and Eileen can’t get to heaven because their souls have been to hell? Did I miss something, because I just finished a re-watch, and that is really, really bothering me. I feel like I must’ve missed something, otherwise that’s a pretty big retcon with no explanation given lol.
