Poy, there was literally no gap between Cata asking for explanations re: sky and him voting her. I do see the point of him jumping on her as soon as the wagon picked up and how he seemed to question it, but I'm not convinced it's scum.
Last time he was scum he offered more of a resistance when asked to vote his mate out.
Will probably look at him more tho. I haven't been paying too much attention to the timeline but I don't put too much into him pushing directions when Sky wasn't even a solid wagon
