Theseus learns from british minister who have just returned from meeting at the MACUSA that his reckless absent-minded younger brother was arrested in New York. Which is strange because some weeks ago Theseus wrote to his dear friend Percy, who just so happens to be the Director of Magical Security, that his younger brother is heading to New York, could you please keep an eye on him so he doesn't get into trouble? Surely he misunderstood something. Theseus immediately heads to US to smooth thing over only to learn that Newt and some woman named Tina are being sent to execution right now. What the hell, Percy!? And without proper trial too?!

Anyway, Theseus figures out pretty quickly that this isn't his straight-laced always-follows-the-rule-of-law friend Percy. You honestly didn't notice this isn't your boss?!

Bonuses:
- Theseus punching Grindelwald in the face because a.) you tried to execute my brother b.) you have done something to Percy c.) you are all round scumbag
- Theseus pretty much taking over Auror department to search for Graves despite not having any authority in the MACUSA. No-one realizes except Picquery, who just lets him do it
- Newt asking "So is Graves that secret boyfriend of yours mum's insisting you bring home for Christmas?" In front of everybody.
