Although that statement didn't really answer his question, Marcus though it might mean that someone had suggested that whomever had had this supposed child of Blaise's had kept it a secret. While he was a little skeptical of the situation as a whole, he wouldn't say anything that might make things worse. "Anything's possible, I guess," he conceded.
Given Blaise's current inebriated state, he wouldn't be mentioning this to anyone until he'd gotten a chance to go over with the other man while he was sober, and probably not even then. It was far too large an issue to be discussed lightly, and Marcus was well aware of how the gossip could blow things out of proportion. "You about ready to head home?" he asked. "I promise to make sure you get there in one piece."
