Zzz was just a random baby zombie the government gave to you to do research on.

Today, you took Zzz with you in the lab for your co-scientists to also have a look on him. But without your guidance, a scientist took Zzz to experiment on. You saw but you just watched as the baby cried like a human.

"D-daddy...!!" It yelled it's first word, while in pain. The other scientists was fascinated, but you felt a pang in your heart by the baby's calls for you.
