My predictions:
Hazbin Hotel cameos.
The main antagonist being either Stella, or Andrealphus, or Striker, or Paimon.
Octavia will forgive Stolas and stay with him, Blitzo, and Loona.
Millie's newborn child and start a family as well with Moxxie.
Supporting cast (specifically Fizz, Ozzie, Bee, Verosika) be more prominent and impactful for Season 3.
Octavia being part of he main cast.
Returning supporting antagonists, Crimson, Mammon, and Rolando (seriously i missed Rolando as an antagonist).
Stella's backstory.
VIv getting her way for some Hazbin Hotel characters to appear in Helluva Boss, for the very least (like i said in the 1st prediction).
Octavia and Loona episode.
I mean yeah, it does make the logic sense.
True.
Yes.
Despite Blitz manipulated Stoles, does he still love Stolas?
