Graves is infatuated with Grindelwald from the get-go. He's been keeping up with news about him in Europe and even though he doesn't agree with most of his views he thinks he's a man with conviction and respects that.

When he gets captured, he decides to make the most of it and seduce Grindelwald to keep him distracted from taking over New York.

They fuck consensually and Graves loves every moment of it. He's loud, vocal and begs for more.
