Undercover

The whumpee has a mission, something to prove, or someone to run away from. The point is: they are posing as someone they are not.

Might be for a specific situation (such as infiltrate a prison for a short period of time), something more risky (like going undercover inside a criminal organization), or even, changing their identities to hide out from someone.

High potential for all the whump that might come with all the things the whumpee has to do to maintain their cover, and with all the consequences that awaits them if the cover blows.
