Four scans from Incredible Hercules #131 and four from Immortal Weapons #1: Fat Cobra.
The dynamic duo wraps up its journey to Hades: Herc's display of devotion to Zeus, in spite of Zeus' constantly being an ass, makes Zeus realize that Herc has successfully broken the cycle of Gods screwing over their fathers, and so he voluntarily drinks from the Lethe. Elsewhere, Cho talks with mom and dad, but his little sister Maddy isn't there, which, despite some obvious concerns, causes him to conclude she isn't dead. He concludes that Athena knew about this, and also that she used to co-control the company that murdered his parents, so decides he isn't going to trust her, and leaves Aegis.
Awww...
Much like the "is Athena a Skrull?" thing, the fact that her potential complicity has been so forthrightly presented upfront makes it highly unlikely she's actually involved.
Elsewhere, Fat Cobra, because of all his boozing and getting whacked on the head, doesn't remember much about his past, so he hired a writer to research it all. Turns out his history isn't nearly as glorious as he thought it was (there's a reason that he doesn't want to remember it), but there were some bright spots:
He also teams up with Nick Fury to fight werewolves on the moon.
He's also had quite a romantic history; most were one-night stands...
