Wow, what a mess.
My first thought is that I'm not a huge fan of either of these wagons at the moment. Of the two, I think it's more likely that UP is still mafia, but his recent posting has looked notably better and his tone feels much more natural. BoomFrog... I don't think see how this plan where BoomFrog is basically offering to get lynched in place of UP really makes a lot of sense if he is mafia, other than possibly as a really desperate gambit to try to scrape together enough townie credit to avoid the lynch... but I don't know that Boom would have felt the need to go there rather than just try to tip the scale a little bit by pushing against UP. I don't see it likely that these two are buddies at all. IMHO it's more likely that these are both Town wagons than both scum.
I think if we desperately need to break the tension and resolve this situation, IMHO the best play is to lynch UP. I'll support that lynch if that's where we are looking at deadline.
That said, I think it's probably in our best interests to take a serious look at someone outside these two. I'm not really going to try to make a case here... I've just got a couple of small pings that probably don't amount to much, but it's enough to make me think maybe I've been reading him wrong. This feels right to me:
