It wouldn't happen. Levi had never met anyone who wasn't at least a little bit selfish. If he ever did, he was certain he wouldn't trust them.
Levi could, perhaps, see why Regulus might have gotten responses like that. Some people seemed to have been here for a very long time and weren't willing to deal with one more idealist on the same topic they all seemed to be on when they showed up. On the other hand, he didn't like people who were assholes either. "Understandable. Erwin is polite. And tends to be curious when he's at liberty to be." But maybe enough about that. Levi was starting to sound a little more than biased. "Sharing a room isn't ideal," he ventured, awkward. "But if I'm ever being a shit, maybe say so."
