Tbh I can see arguments for Rocket either way. It's weird that SS tunneled so hard on that "investigation result" despite no one else really biting on it. On one hand, it could've been him trying hard to push an easy mislynch candidate and set up PL as a round two mislynch over his "lie". On the other hand, he may have been looking for town cred in case Rocket did end up hanging.
In the town!Rocket scenario, I think it makes more sense for SS to push that mislynch wagon if there are others who are open to the idea of lynching Rocket. That really wasn't the case though, so it just seems like such a bizarre thing to do. I could also be grossly overthinking this.
I keep going back and forth on this so I'm just going to leave him as a fairly null read at the moment, but he still belongs firmly in the PoE. He's done nothing but throw a vote on PL to avoid a god-kill.
