I just had a lovely thought, though I am sure it is not possible at this time....but as so many people (including myself) are swept up in Downton Abbey fever, I thought it would be SUPER if Nat were to make a guest appearance on the show. He'd sure make a great buddy/colleague for Lord Grantham and who knows, maybe they could weave in a little romance somewhere (though not with Cora Grantham, as in this past season - that was a bit much). I bet he would be great on the show!
