I targeted Space primarily because of Faust's last posts yesterday.
(This is also the reason I prompted Faust to give his reads before end of day.) RR flipping town means I definitely had to shoot last night, because it would remove me from the lynch pool today. Also hitting scum was 50/50, not terrible odds. Shooting town means today would be LyLo, but I'd be verified and we'd have a decent chance. I'm not certain if I would have shot if RR was scum.. it would depend on reads probably, though it may have been better to save it until tonight.
Faust listed me, Space, Iguana as his primary scum in case RR was town, and Space seemed more likely than Iguana. I preferred to shoot on his reads, since the chance of Faust having no scum on his scum reads is pretty small. I also didn't have any really strong read myself to choose someone different.
