It's the fact that he lost that hard. Generally, one would assume scum would win, at least a little bit. He played fair when, as scum, he honestly has no reason to because he needs to get into the bracket somehow unless his team has given up all hope on him and have cut bait. Given that they can't communicate, I doubt it they've said anything to this or really to each other. It's nothing incredibly major but, again, it's still worth looking into and weighing into your reads. Losing that hard should definitely put Kantrip in a better light.
I'm saying look past it because you're getting caught up in it and not looking at his other actions. You're looking at something you know he does as either alignment and allowing it to distract you from what he's doing. C'mon Ran, this ain't rocket science. You're assuming he's faking it but I see no justification, just assumption on your part.
