So the wagons yesterday were all on 3 of the 4 people who contributed the least. Looking through the vote history it's hard to see any votes that were made to save someone. The votes that pushed shock/w3 ahead of math came off of math, and most of the people on shock/w3 were on both at some point. The main exception to this is Naii, but w3 voted him so that doesn't go anywhere.
There are two things i want to bring attention to, though. The first is Oa's vote on math. This was the first vote that put someone to 3, and in my mind was the one that solidified the trains for the day as it caused math to put a self-pres on w3. It's Day 1 random voting so you can't put too much stock into it, but that's what I saw. The second thing is andre. Right at the deadline, shock was looking like the lynch with a 2 vote lead, but when shock said he had info, andre tied it up to pressure him to reveal it. After he did, andre switched right back to seal the lynch. The only thing this accomplished was to clear Torb from GN, which is pretty helpful for mafia to know because he's a high priority NK target. One interesting thing about this is that when andre switched his vote back, rather than changing it like normal, he copied the earlier vote instead, so his name only appears as the second vote in the final votecount instead of the hammer that it was. Maybe intentional, maybe just lazy. Either way, this is where I'm going to start looking tomorrow, I'm inclined to believe that all three trains yesterday were town.
