Jack looked confused for a moment as Gray spoke to the kid. He didn't know Gray knew any other languages. Then he got a better look at the boy and cursed quietly to himself. He turned to look at Ianto. "Concentration camp." There was a pain in his eyes. He had seen people like this when he had been stuck here in World War II, after they won the war. After he had been made immortal. "He'll need a light broth." Real food would have to wait. It would only make the boy ill and possibly kill him.
He turned to Gray. "World War II, the holocaust. This child was in a concentation camp." he noticed the badge. "For being Jewish." Then he asked Gray. "What did you tell him?"
Eric relaxed a bit as Gray told him there was no need to worry. He hardly had the energy for that anymore anyways. He supposed he could see the resemblance between the two. Then there was a bunch more speaking in that other language. He was more and more sure it was English.
