Alright, now that I've had an overnight to consider it, I would agree with RM that Supa is starting to look more like a part of the Resistance. The questions that he's posing don't look anything like what we would expect if he was on a team with someone else. That being said, we know that either Earth or RM is a Spy, and if it's the former, it wouldn't be too terribly surprising for Supa to just be out of the loop entirely because of a lack of communication. So, at minimum, I don't see a Supa-RM Spy team happening. Right now, Supa is the one person who I see as least likely to be a Spy.
I also think that it's unlikely that there is a Pie-RM Spy team, though I'm less confident in that one. RM was the one suggesting that, as a Spy, he'd have good reason to want to sabotage on Mission 1. I doubt that Pie would be on board with that, but Pie wouldn't have been in the driver's seat, so he may have posted about it being a "bad move" with the express purpose of distancing himself from the decision as much as possible. That being said, given the short time between the start of Mission 1 and the start of this discussion, I don't see it as all that likely that they were in chat together, as it likely would have led to at least some amount of argument between them.
All of this is focused on a possible RM Spy. It's a tougher call with Earth being the Spy, though right now, I'd say I'm leaning towards RM being the likelier of the two by a small margin. With that assumption (first to admit, it's based more on intuition than actual evidence), that would just leave me and Oro as possible Spy partners to RM, which means that I would advocate taking Oro off the current team and putting Supa on in his place. If I go by the assumption that it's Earth and not RM, then Oro would still be a plausible Spy among the remaining players (Pie's response to my suspecting him makes me think that it's not him, and Supa's being so uninformed still doesn't fit his normal play as scum in mafia, where he usually at least stays informed). There's always the possibility that Earth and RM are both Spies, though I'd say that is the least likely of the three and then it doesn't really matter who we leave off.
So, at least until someone gives me a good reason to change my mind, I'm voting no.
