Oh, are we seeing Dr. Watson downloading Ratchet.exe?to add to these observations, I notice one of the reasons he's so hard to parse as scum for people is him being emotionally disengaged. I can't read players well at all unless I get some kind of emotional entanglement at some points of the game - not just ire or annoyance, but being frustratingly defeated genuinely regardless of their alignment.
I have to navigate purely by the logic he presents toward the class. And that's very difficult as it gets to the brains of the matter - essentially he forces you to skip your innate emotional experience and just read it straight
I think I have some knowledge on a very specific tell but I wanna see if he keeps doing it

From your observations that may or may not be accurate, what do you make of Ratchet with your assumptions in mind?
