When Newt find Graves, he is locked in a cage behaving no better than a wild beast. All thanks to torture,spells, and being force-fed potions in order to get information out of him.
So far no one on the rescue team has been able to get near Graves, so Newt gives it a try and asks the group to leave as to not antagonize Percival any further.
After an agonizing two hours with no sign of Scamander, the rescue team heads back.
They return to see Graves sleeping peacefully with his head on Newts lap, while Newt whispering comforting things to him.
At that moment, Picquery decides its best to keep Percival under Newts care, until whatever magical effect he’s under wears off.
