Here's my season 8 theory:
Hank will learn from his experience in, let's call it comaland, that he has an innate gift. The power to guide "souls" out of Comaland. A power accidentally instilled through the cloning cycle of the boys "souls" reuniting with their clone slugs at least 100/200+ times if the zombies from 'Assisted Suicide' are any indication. Hank will work on his ability, maybe with Orpheus, while Dean stays in school. (A side note that it would be funny to see Orpheus life's work get btfo by a naturally adept Hank). Hank fucks Triana. Dean has the ability as well but as he gets tied to more earthly shit it's not as strong as Hank. The season/series finally will have Rusty and Malcolm get majorly fucked up and sent into Comaland together. Maybe they do one of those "we're trapped together for 10 years but it's really only been 10 hours IRL" and they work out their problems. Only for Hank and Dean to start arguing about Serina. Malcolm and Rusty step in and give some advice and everyone realizes how fucked up their lives are and the show ends.
