We’re missing some time between when Pentecost sent Hermann off to find Newt and the two of them drift. I’m pretty sure this isn’t what happened but a girl can dream.
Until proven otherwise, I’m pretty damned sure this happened. I mean, after Newt drifts that first time, Hermann is VISIBLY DISTRESSED. He is so obviously worried, and then for Newt to go out into Hong Kong immediately after that to meet with a black market dealer with the warning of “DO NOT TRUST HIM” and then seeing Otachi rampage around where Hermann knows Newt IS, oh boy. No. Hermann was probably just losing it a bit on the inside.
