For me it's less about him saying the game is going nowhere, I totally agreed with that up until this point.
The reason I'm currently voting for him is because his reason for voting for Nick is very weak (though that's not a big issue because this is still RVS, I get that) but also that his vote that he claims he made in order to move the game in that direction isn't moving it in that direction at all, since he doesn't have any good reasoning to back up his claim currently.
When NP claims he hasn't moved the game forward after wanting it to be moved forwards, he argues back by saying he's pushing for the game to move forward by voting for Nick.
I personally believe his counter-argument makes absolutely no sense as voting for Nick doesn't push the game forwards, which he claims is the specific reason why he made the vote. So his actions and what he says the reasons for those actions are don't line up, making me suspicious of him. It gives me the feeling of him trying to hide something or not having a good reason to make a move like that, and I believe if you're town, you have nothing to hide by telling the truth.
Let me know if you're still confused on my reasoning, I hope I'm explaining everything properly.
