Spoilers for S02E12 of Helluva Boss.
I can't work out why Octavia hates Stolas now. Stolas leaving Stella and dating Blitzø instead doesn't prevent Stolas from being her father. After he lost his title, he tried calling her repeatedly, and she knows that. Surely she didn't expect him to hang out with her while he was having his prior mental breakdown. She honestly can't be upset that Stolas was taking meds for his depression. It doesn't make sense.
