To recap:
From my POV I know the scum team has to be Sky/Smark or Pendex/Smark. I personally believe it is the former. Either way Smark is guaranteed scum. I can't get Sky or Smark lynched, so lynching Pendex means I am going ALL IN on EXACTLY Pendex/Smark being the team. By no lynching Sky has to give a result on Smark. If I'm wrong and Pendex/Smark is the team, she'll get a guilty, and so mafia will have to kill her to prevent this. This gives us our answer, it's Pendex/Smark. Game over, town win.
If I'm right about Sky/Smark then Sky will survive night and give a town result on Smark, and Mafia will need to kill someone, which will either be prevented or not, either way we get more information.
From your guys POV, if the team is me/Pendex, then this plan guarantees it and so there's no reason not to do it.
