Oh sure, whip out logic on us.

Alright, let us:
Suppose Walter is a one of those classic liars or truthtellers (or knights and knaves) from that weird island.
So, I would ask him, "what would be your answer if I asked you about your allegiance to The Order (for it / against it)?" Notice I'm asking a question that depends on the answer to another question.
If he's a truthteller, he would answer truthfully so whatever he says is the truth. He says he's with the order, then he is. He says he's against it, then fine, he's anti-order.
Now, if he's a liar (always has to lie, can't avoid it, don't ask me, that's how these things work), then he would lie about his allegiance if asked directly, so if I had asked him directly, he would say the opposite. But, since my question was about his answer and not his true allegiance, he can't answer with the opposite allegiance to that question, because, as I've shown, that would have been his actual answer and he would be telling the truth. Thus, in order to lie to my indirect question he would have to answer with his true allegiance!
Either case, regardless of him being a liar or a truthteller, whatever he says is his true allegiance!
Of course, he could be a spy and be able to choose to lie or tell the truth whenever he wants.
