I don't know if anyone watches World Beyond, but in the post credit scenes, there is a scene where somone is playing an old video of the guy from the CDC (in season 1) talking about a new vatiant in france that they hadn't seen in the US, Variant cohorts. Someone kills the french woman watching the video, she turns pretty qickly, but instead of being a normal Walking Dead walker, she turns more into a '28 days later' zombie. running fast to the door and trying to get it open...
This opens the door for maybe a European spin off that a little different.. They talk about teams and causing it and making it worse.
