"I'm not so sure, cause I wastched the interview too, and then season 6, and he might be refering to that columbian woman, rose, cause there was definitly something implied there, and he also said to callen in legend 1, that he had 4 wives, and not 3 as he tells everyone else, so assuming that he isn't mentioning shannon, because he usally doesn't he could be refering to this mysterious 5th wife. and he has kept this woman hidden from the rest of the team, so he probably won't have mentioned it to people who don't already know, and we could assume that callen knew him there, or he figured that his secret was out now. this would explain why he said three wives. cause it didn't seem like a slip of the tounge in the interview, it was a deliberate comment, but then again I could be completly wrong, this is just speculation"
