Somehow I think Argus could be Brandon. Not sure, but he would have guessed the secret condition,if he had the first half.
If SG is Odysseus(looks very much possible), then IDNE, Twin Bro, AI just might be Nestor, Diomedes and Calchus not in the same order. Or one of them could be dawh, PT or JS who are pulling a trick and not voting for SG. The good thing if our assumptions re right is that Brandon is not a recruited Achaean, which makes him a probable candidate for an indpendant ot a Monster.
