If I were scum, I would have invented a universe where there was maximal consistency with my prior play, and I would try to position myself as the logical party/voice of reason. I would also more aggressively position a specific player as The Bad Guy. For real-life examples of what I'm talking about, refer to D3/D4 of
Fables or to D3 of
Disgaea D3.
In Fables, a just-NK'd daycop's mason claimed a guilty result on me, and I responded by linking a bunch of connections on the part of the mason to deadscumfriendSP and fabricating/misreading inconsistencies in his claim. He was lynched. Then D4 I avoided certain suspicion by claiming that I was masons with my remaining scumfriend (DGB) and cherry-picking D1 exchanges between the two of us as breadcrumbs. NL D4 (I had been made voteless), no kill N4 (there was a busdriver alive), then we lynched the busdriver D5 to win.
In Disgaea, a Cop claimed a guilty result on me D3, and I used context (I had just let slip that I was not his rolename, e.g.) to make it seem like he was fakeclaiming. Then I argued that it made more sense to lynch UK (not the Cop), because fear of scumfriendUK's death was what led the Cop to fakeclaim something that would out him, etc. This one almost worked, but the last townie wanted to lynch the Cop proper and got suspicious that I didn't want to do so (he suspected Mafia Usurper shenanigans; I just didn't want my scumfriend to have to follow me to the other wagon), so he lynched me.
I could give other examples, but they are ongoing-where-I've-flipped.
Only other example is that I did have a little bit of a long wagon D1 in OS as scum, but it was because people thought I was scum with townVaya. Then I was NK'd by SPSK N2.
So, that's my self-analysis. As town, instead of trying to make up a Fairy Godfather to save me, I just reflected a little and answered honestly. The result isn't particularly compelling, but it accurately characterizes my feelings about SC.
