"You're a Kraut--I mean, a German, for one," Carter pointed out. His grandmother had been German enough to teach him the language but that was so far back that it hardly mattered. "And I'm an American.I knew a guy who looked exactly like you but we weren't related at all."

That frown eased Carter's laughter. The 'uncle' looked genuinely upset that Carter didn't know him and that just made the situation uncomfortable. Was it possible that Klink had actually gotten himself a wife (because you couldn't make kids without marriage) and had children after the war was over, and this one had sought him out. It seemed crazy. Especially when he couldn't get Carter's name right.
