So Grindelwald is a manipulative little shit and I kinda love that.
He's had Graves for a while and the man is nothing if not stubborn. At this point his prisoner is expecting to suffer some more then die and he's hell-bent on not giving Grindelwald the satisfaction of breaking him before that.
Then Grindelwald makes him an unexpected offer "Suck me off and I let you duel me"
He refuses at first, but then this tiny bit of hope keeps gnawing at him... So he accepts.
+ Graves losing after landing a few solid hits (whether Grindelwald let him or not is up to you) ++ Getting frustrated because he -almost- had him +++ Begging for another chance
