There are other tells in production too. They don't seem to have moved away from the last person coming down for breakfast being the other potential candidate for murder, but perhaps the idea that they'd have to send down some Traitors last in the second series has enabled them to get away with that.

And it's not always a tell but the order the producers have the voted revealed at the round table can occassionally give a clue as if there is a close vote with a traitor potentially at risk then having another traitor reveal that final vote is perhaps too tempting for the producers.
