It's the fact that you looked at his interaction with Aurelian and immediately went, yup this is definitely a bus. RDK was on him from the start and just drove him straight against the wall and provoked all those unflattering self-defense posts that caught other people's attention, it's just beyond me how you can look at that and instantly think it's a bus, so it strikes me as fake and as trying to act like you're suspicious of one of the towniest players in the game just to look contrarian. You did the same thing with Poyser in Xmas mafia and you were scum then so I see clear parallels.
What I will grant you is that RDKs play has fallen off a cliff since d2 and it's got me intrigued as well. I pretty much read him town out of the gate and even moreso after Aurelians flip, but I'm also aware that as scum, he's only able to fake his scum meta for so long and that as the game progresses, he struggles for content. So by now I'm not 100% on him being town anymore but it's still a good 80% I'd say.
