Maybe; I'm not saying that I think it's a lie, but that's what the crew seems to be pushing on Twitter. Regardless, he could have a different reason for wanting to lie. I've said elsewhere that he may have wanted to lure them into a false sense of security so that they wouldn't go digging into his real past. As long as they think he's Fergus McLeod and nothing more, they'll assume that they have a leg up over him, when in reality, they're just buying into what Crowley wants them to. All Crowley would have to do from that point is play along.
