"I'm his descendent, Desmond. Many, many centuries removed." Which was true outside of the fact that Desmond looked more like Altair than his own father, but Desmond didn't question it really. His DNA traces to the three of them were strong, so maybe the looks passed that way too. Or it was a freak incident. He could tell something was different about Malik, but assumed from now he might be from later in the timeline. ...not too late, obviously, as he was alive.

"I know a lot about you from, uh, stories that were told." He wasn't entirely sure he should jump right to 'I know almost as much about you as your best friend.'
