Nowlet me start off by saying that I am freakin enjoying the story arc Donny Cates and artist Ryan Stegman are presenting forth, from main story issues and spin offs from the horror inspired issue of Seperation Anxiety to the Tragic tale of the Judge in Symbiote Spider-man and not to mention the Goofiness the Deadpool tie-ins they have got me hook line and sinker.
The issue continues where the third issue left off with Bruce Banner( or better Hulk) bonding with the Venom symbiote.
Eddie ( now without Venom) moves Dilan away from the ensuing Carnage back into the safe room.
With Spider-man guarding Norman and Dilan, Eddie arms himself with America's Sheild and Misty Knight's metal arm( atleast I think it is)
And elects to fight off the hordes of Carnage's army.
In the Fight a Venomized Miles Morales attacks Eddie, in which then shocks him with a Venom blast ridding him of he symbiote.
Meanwhile Carnage attacks a Venomized Hulk and collects the Symbiote from having completed his collection thus fore transforming into his final form in order to awaken Knull the Symbiote god.
All the while Normand Osborne ( still thinking that he's Carnage attacks Spider-Man who is protecting Dilan and Norman Jr.
Eddie then having been informed by Miles that the Maker's machine does extract the codex of a symbiote and destroy them, it collects them.
