Freeky and BDS should automatically be suspect, whether they are joking or not.
By the rules in this version, two spiders will know of each other, while the third won't.
If Freeky and BDS are the spiders and know of each other, it makes sense that they would then put it all out there in a gambit to build The Machine as early in the game as possible. THey could then play it off as they were just joking.
Unless of course they are just joking, but this new rule makes it possible for the spiders to use this tactic.
