Infected

"What if the zombies are contained and it can't spread?" Asked Sean.
"Then it won't be called a zombie apocalypse would it? Apocalypse means the end of the world and if the zombies are contained, they can't spread their virus world-wide and bring an end to humans. That is, unless the guardian of the zombies become infected..." Alena stopped speaking, hoping her point was across. She was also curious why he wanted to talk about this. There's no zombies on this earth. Fear rippled through Sean.

Zombies are coming to planet earth! Sean has his suspicions before they even populate. He obtains some information that leads him to something he never wishes to be a true.
