The way the story appears, at least as the showrunners intend, is that Jason Blossom was planning to run away with his pregnant girlfriend.
And now that he’s seemingly taken his own life, was Cliff Blossom the second death promised this season?
Rather than seeming shocked or afraid, Cheryl was unmoved – marching quietly to her family dinner table and revealing that her father had done “a bad thing.”
Since his father seemed less than disgusted at their shared genetics, we can only assume that Cliff was motivated by something else.
