So Grindelwald's successfully taken over as Percival Graves for the past few months, it's looking good, he's got a plan. What he's not expecting is one very angry magizooligist to suddenly come bursting through MACUSA headed straight for his office because his fucking boyfriend stopped communication cold a few months ago and he's PISSED. And Newt knows right away and pissed goes straight to 'furious terrifying man with a war vet for a big brother, an auror for a boyfriend, and a whole suitcase full of potentially lethal animals'. Grindelwald cannot withstand the wrath of Newt.
Graves is lowkey turned on when he is rescued and finds out his boyfriend scared the worst wizard of their age half to death.
