People who've been here a long time... Zero couldn't say he knew many who fit that description. Harvey Dent was the first one to come to mind, although he couldn't remember exactly how long Dent said he'd been here, if he'd ever said anything about that in the first place; Zero just figured it was quite awhile since Dent seemed so experienced. But otherwise, there was...that man he'd met on his first day here, the one who'd been here before the military had taken over the Institute. What was his name again? He remembered the face and voice more than the name...oh well. Then there were Lana Skye and Nigredo, both of whom Zero was guessing had been here awhile based on their experience, like Dent. That was about it.

Would one of those people know about Marc, and how to reach him? Couldn't hurt to ask, in any case. The worst he could be told was 'I don't know'. (And wasn't that the common response to any question here, anyway?)

"Yeah. Someone has to know." Zero uncrossed his arms, resting his hands on his knees; he continued to think hard in the meantime. "It's probably something to ask over the board, actually."
