Roger is an identity taken on by the active Victor when he is hired by Miss Lonely Hearts, whose real identity is Adelle. He is a suave Englishman who is hired to be Adelle's boyfriend for a day every so often.
The two enjoy fencing together, and Roger has stated that he wants to run away with her. Roger is aware that she is the head of the Dollhouse but not that he is a doll, and he knows her by the name of "Katherine". Roger comforts her when she finds out Laurence is an NSA spy. Adelle later came to the realization that she doesn't need Roger anymore and will no longer imprint Victor with him. 
Around six months later, Adelle is seen sleeping with Victor as Roger again as Victor's contract is about to be up. He breaks up with her, saying he's in love with another woman. Roger doesn't know it, but it is actually his love for Sierra shining through the imprint that makes him break up with Adelle.
