It's not about calling someone out, it's about being right. I don't think, as scum, Ultra subs in, and then pushes the town masons and then doubles down when you can evidence it. His solve actually makes sense if you allow for the masons to be less than confirmed in your mind. And also, there is not many that fit in a scum team with him. He's not going to be scum with Nutmeg. When he subbed in, he took the attention away from Reloaded and onto Cata/Stargate - he's unlikely to be scum with either. That leaves Gad and Reloaded exactly. It's not impossible, and there is an explanation for his behaviour that fits a scum mindset too (that he knew he would look bad after pushing the masons and decided that doubling down was the best way to WIFOM it), but I'm not all that compelled by it. Would much prefer flipping in Cata/Stargate, I think Stargate's posts today have been harder to reconcile than anything Ultra has said too.
