Be aware of doppelgangers!

(Doppelgangers: a evil creature who can shapeshift in a specific person to pretend they are them. In which, The D.D.D headquarters get involved with the doppelgangers after the doorman or doorwoman called and reported a suspicious person who they thought were a doppelganger.)
