Like some of you are acting like Cal's vite on Polar there is bus of the century. As scum he either watches the CFD happen and runs the risk of a massive confirmed town block, or he tries to get ahead of it. He then uses it to make himself look great in comparison to others and then pushes them off the back of it. It's how scum should be playing it. Sure he could join Gad there but given he barely commented on the wagon before then he would just be looking awful long-term.
Then come Day 2 he says the Gad wagon is awful which is his first meaningful comment on said wagon, and leaves his analysis as that. He gets very overeager pushing things because he's now got the thread standing to do so, none of this is bad play imo. If I'm wrong then I'm wrong, but ti me I think there's a very clear line of logic to his play where he's scum that would ultimately be to the benefit of his team. So if it turns out that scum just rolled along the floor and watched it all happen then they're not a threat to winning at all. If Cal ends up being town Melkor would go straight to immediate PoE because Cal is really the only slot left that, if scum, did anything to affect the game.
That's what I'm basing my PoV on, I don't think it's unreasonable or requires anything especially convoluted.
