What Happens in Episode 4?
Mark is still reeling from killing Rus Livingston — or rather, what Rus had become after being infested by Sequids — and from the rage he’s finding increasingly difficult to control. He visits tailor Art about returning his costume, claiming he doesn’t deserve to wear it anymore.
Meanwhile, chaos is erupting in a place Mark never expected to visit.
Damien Darkblood and his clan are engaged in a battle against Volcanikka, who is trying to seize control of Hell using a powerful artifact called the Vial. The fight goes badly, leaving Domina gravely injured. Damien attempts a ritual using Nolan’s blood intending to summon Omni-Man — but instead, Mark is pulled into Hell.
Once in Hell — which demons call the Under Realm — Mark learns that Volcanikka hates humans and that if she continues to rule, she plans to release the Vial to the surface, unleashing ancient evil upon Earth. Mark grudgingly agrees to help, on the condition that he’s sent home the moment the job is done.
The Ending — Three Bombshells in Five Minutes
Bombshell #1: Volcanikka is defeated. Mark retrieves the Molten Crown, and Satan’s authority over Hell is restored. Crisis over — for now.
Bombshell #2: Satan hints at coming to Earth. After Volcanikka’s defeat, Satan sends Darkblood back to Earth as his spy. But then Satan ominously says: “I feel that there may be a need for my scorched flesh to be kissed by the gentle heat of the sun once more.” Darkblood responds: “I was afraid of this.” IMDb Satan. Coming to Earth. That’s the threat hiding at the end of this episode.
Bombshell #3: Omni-Man is alive — and the Viltrumite War begins. Just as Eve is preparing to tell Mark about her pregnancy, the moment is completely hijacked by the arrival of Omni-Man and Allen the Alien, who are there to announce the beginning of the Viltrumite War. And in a deeply symbolic moment, Mark finally puts his classic yellow and blue suit back on. IMDb

FAQs
Q: Is the Hell storyline in Invincible Season 4 Episode 4 from the comics?

Q: Does Eve tell Mark about her pregnancy in Episode 4?
No — Eve is interrupted right before the reveal when Omni-Man and Allen the Alien arrive to announce the start of the Viltrumite War. The pregnancy reveal has now been delayed for a fourth episode straight, building unbearable anticipation.
