Credence fell in love with Graves when Grindelwald was using his identity, and Grindelwald encouraged that desire to better use it against Credence. Now the real Graves enters his life in an effort to right the wrongs Grindelwald did by taking Credence in and educating him. Credence is grateful but at the same time he hopes to be seen more as a lover than a responsibility.
