Markus nodded as she questioned him, letting her know she was entirely serious. However, when she asked what he had been getting up to, he would pause for a moment—considering how to word such things in public.
“Well, I discovered the office and their investigative services when trying to gather some information my first week in the city,” Markus said, choosing his words carefully. He assumed it was safe to say that much, seeing as the Exchange's actual front was as an investigation agency. “Then, about a week later, I had a bizarre encounter at a transit station. And since then, I haven't had much time to breathe. So much so that I absconded to Europe for a few weeks to get away from it all.” Markus finished.
He assumed if anyone were to know about the weirdness in the train stations, it would be someone with the Exchange, seeing how many people Markus had met that had similar stories to his own. He also knew most people overhearing them would assume he was talking about flickering lights or maybe encountering a drunken individual.
