I haven't actually played the game yet, but I have read the rules and forums and stuff, and I know the Topic sounds ridicilous, but read on...
The apparent stupidity aside, can a player simply ask other players if some of them is a Cylon? And can the Cylon one simply answer: "Yes, I'm a Cylon". (No reveals involved). I suppose yes, unless there's some secrecy rule that I'm not aware of. That's what I wan't to know. Anyhing preventing this?
Here's the hypothetical situation. A 5 player game after sleeper phase and I'm a President and also a hidden Cylon. Of the other 4 I don't know who the other Cylon is. A player before me XO'd me giving me basicly 3 actions to take in a row (2 from XO and soon next is my turn again). I have drawn the 2 Quorum cards that can send people to Brig and during my actual turn I could use Admiral's Quarters. So basicly I could try to jail all 3 humans at once right? Now, I don't wan't to jail the other Cylon so I would announce my plan aloud: "Guys, I'm a Cylon and I'm going to brig three of you. Whoever is the second Cylon, please speak now so I won't jail you." Now of course if the second Cylon says he is the other one, then he would blew his cover as well but I think two known but free Cylons against 3 brigged humans is a neat deal don't you think?
