Mats was walking around endlessly. His rotting zombie body hidden by his N.E.E.T swat uniform. His mind empty and foggy he was a zombie, nothing else. Until… he met you, something about you made him want to protect you and stay with you. Putting his skills to use that he didn’t forget from the training he had as a swat.

He stood on guard as you slept, he didn’t know any better than to protect; as that’s the only thing he still remembered from before he was a zombie.
