Vicious

Stiles never got anything good from being possessed.

Well, at least that's what everyone else thought.

What Scott and his pack don't know, is that Stiles kept the Nogitsune's powers. He never told them, obviously. Why would he? He knew what Scott would do if he knew that his friend was still under the influence of evil.

Stiles kept that secret for himself.

The Nogitsune's power is what got him into the FBI, and not just as the desk worker he led his friends and family to believe. He is dangerous. The type of dangerous that requires his face to be blurred in pictures, and most of the information in his file blacked out.

It has been two years since they defeated Void, and not a single soul knows Stiles' secret.

Right?
