In venom 4 Venom gets back to eddie somewhat quickly, but venom is still pretty weak so he's unable to transform or transfer back to eddie. The rest of this part of the film is split between Eddie's and Venoms POV as venom tries to communicate ( unsuccessfully ) with eddie.
Half way through the film, Late at night, Eddie decides to take a shortcut thought an alley way and gets held at gunpoint for films reasons. Film stuff happens and they shoot at eddie. Eddie flinches, but just before he closes his eyes he sees from the bottom right of his vision a cockaroach seemingly jumping in front of him just in time to block the bullet.
The thugs are surprised and terrified as they try to comprehend what happened in front of them. They just saw a cockaroach appear from a dark corner, moving in a speed that should not be possible, somehow jumping and stopping the bullet. As they are still trying to understand it all, they notice that not only is the bug not dead, but its currently skittering closer to their location.
In a panic the thugs start shooting wildly both at eddie but more at the cockaroach. To the awh and horror of everyone the insect moves in a hard to see flash bodyblocking every single bullet. If it wasn't for the fact it was a bug it would almost seem magestic. The thugs decide this is not worth it and just run away.
Eddie stands there dumbfounded as the cockaroach watches the thugs run, when they are out of sight it turns around and stares at him. Having been familiar with the unnatural for over a year, and feeling desperate at the first sign of it coming back , he asks "Buddy, is that you?". His eyes tear up as he sees the bug jumping up and down in what he assumes is joy.
The rest is now about the evil guy thats hinted around the first half of film. However throughout the film at what seems like random moments different pieces of a qr code appear, small and hard to find. Putting all the pieces together and scanning it takes you to a video of Venom and Eddie fucking nasty style.
This was meant to just be me writing down an idea that turned into fanfiction.
