These are highly synonymous. I just answered your questions. He has a mask behind which he can easily and reasonably hide and claim town.Why do you find him to be acting suspicious then? Just because it is possible that he is scum? It is possible that I am scum too, and I'm even defending Ifrit. Why don't you vote for me? How is me acting the way I do to show I am town any different from Ifrit's?
Also, I say we do it the other way around. Let's lynch Ifrit first, and if he flips town then I'll take the knot next, whether I like it or not. If he flips Mafia, then I'm off the hook. Whichever way you decide, him or me first, it'll work out the same way.
