Graves would be so pissed though, don't even pretend. He would be so angry he was way past livid; he would be living in this zen mode: cold, liquid anger flowing through his veins. So he calmly (pissily) busted himself out, calmly limped to MACUSA, calmly limped again to the subway, calmly sneaked inside. He came upon Grindelgraves spewing bullshit and hurting his aurors and just. Exploded. It would be glorious. Grindelwald never saw that slipper coming.
