Newt didn't get away unscathed from the subway battle. The lightning he got hit with left marks all over his body. Not that he planned on bothering anyone by telling.

Good thing: His arms and face are unmarked, so it's easy to hide.
Bad thing: He is left with cardiac arrhythmia which makes itself known at the most unopportune moments. Being hit with cruciatus several times certainly didn't help either.
Embarrassing thing (well for Newt): Collapsing into real!Graves arms a few days after the battle. That's one sure way he didn't want to be found out. Even worse...Graves plans on telling his best friend - Theseus. Could things get any worse?

+ for Credence surviving and hero-worshipping Newt and Tina
++ for motherhenning from everyone. Newt the little cinnamon roll that he is, deserves so much love

I'd love to see some hurt/comfort because the way Grindelwald tortured Newt must have left at least some injuries.
