If you’re the guy who was looking forward to another Carrion, then read this. Of you’re not, then don’t. I suspect most of you are in the second bucket.
A SHIELD scientist is working with Miles Warren’s virus in a lab, gets exposed, and becomes another Carrion. He zombie-fies New York City (sounds cooler than it actually is), and Spider-Man looks for help from Tinkerer and High Evolutionary but gets turned away. So, instead, he takes care of it, with the help of SHIELD (although Carrion does escape).
The punch line in the end is that the SHIELD agent who helped engineer the zombie cure is actually High Evolutionary, who decided to help after all.
If there were big plans for a new Carrion it might make sense to have a one-shot devoted to his origin, but there are aren’t and it doesn’t.
