yes, i believe the reason was dabbs/ and the other writer wanted jack in future seasons when he is old enough, they wanted the nepo to be the star of the show. this was according to the interviews, they were like avoiding the question why jessie isnt coming back. i think the actor was interested in coming back as older anti-christ, if he wouldve been recasted. likely the reason why Darkness was quickly squared away, because “jack had to be the only GOD”

The jack chracther was a cameo in the BOYz, dint realize he was in there, im guessing his career isnt jumpstarted like they wanted.
