Wow... a lot has happened since I went to bed last night. I've been working on projects all morning so I'm just now checking in.
I'm tired of the "Wood's played before, he's quiet, so he must be an infil." (I'm looking at you Twietee and Fenris) The team is more than capable to analyze situations without my help every five minutes. But since it is continually brought up, here it goes.
The infiltration has played a really weak game so far. If I were an infil, I would have voted for the first one or two missions to succeed, gaining the trust of the other players. You can't suspect people if they are helping the cause, right? I'd give the agents quick points, and keep them guessing as to who could be the baddies. Then I'd work to get two infils on the final three or four missions to fail the votes. By that time, the plot cards may have been used, and the odds of successful infiltration is higher.
I would not fail the first vote, and I certainly wouldn't do anything stupid to make it obvious that I was an infil--like going against team instruction (looking at you Astroboy). At most, I would fail the second mission at the risk of exposing an infil, and then sacrifice that player.
It's obvious that Astroboy is an infiltrator, I'd focus my attention back to the first mission. Who was on the mission when it failed? We've cleared nearly everyone, which is why I forced Koodauw to vote publicly. He has to vote "success" or he won't get selected for the next mission. I'd be careful though, because any false sense of security that public voting brings with it, can quickly disappear if he's an infil. At this point, it might be a good Infil strategy for him to fail a mission once it reaches mission status, because you all trust him and we have no more "no confidence" plots.
