In Mass Effect 2, Smokey is a proud member of the military. Her hair is shaved by choice. She’s proven herself physically and mentally but some just can’t get past the visual. She’s by the book and doesn’t let emotions interfere; she is loved and hated for this.
In Mass Effect 3, Smokey has been out of the military for a while. Public perceptions and the political climate have somewhat jaded her. She embraces personal identity: lgrows her hair, wears more makeup, and parades her femininity. She doesn’t take a mission at face value; she weighs against an inner mission.
