For the record, Affinity was right on my day 2 shenanigans: what I really wanted to be sure of was Alex's alignment, because scum getting away with a cop claim would've been disastrous. If Alex really was a cop, he'd come back on day three with the right answer (albeit, probably a little perplexed about it) and we'd at least be sure of his sanity. If we was scum, he'd probably come back saying "scum," I'd roleclaim, and we'd lynch him. Of course, I couldn't make it 100% obvious what the gimmick was, because then a theoretical scum Alex could've guessed what I was up to and tailored his "investigation result" to match. So I had to play like I'd be doing something overnight instead of, y'know, being a passive role. Apparently I was too cryptic for Alex, though (probably doesn't know me well enough; Super got it, at least!) Oh well.
Fundamentally, it didn't make a difference whether or not scum knew I was up to something just as long as they weren't sure on the specifics; if they'd roleblocked me, I would've been notified and could've taken this into account the next day when Alex shared his results. Roleblocker on Alex could've fouled things up (that or me getting killed, but I knew that was a risk going in since the role list included Hitman). I figured, worst case scenario, I'd make myself a target and scum would focus on me, freeing up the active town roles for the night.

PM'd Rat right after I got killed guessing Bard/Affinity for the remaining scummies. Half right!
