Let's see what would happen if we left silverspawn out though.
UoS is scum -> 10 people alive, presumably one of them is scum, 5 are ICs and one is pretty trustworthy me.
Silverspawn is town -> silverspawn kills 2 suspicious people other than himself, scum kills an IC, leaving us with 7 people alive, out of which 5 are more or less confirmed non-scum, one is silverspawn, and one can be copped by me. Then, either the last scum was killed by silverspawn already, or I copped him and we can lynch him tomorrow for the win. This is great.
Silverspawn is scum -> silverspawn kills 2 ICs and outs himself as scum. This leaves us with 8 people alive and we can lynch him tomorrow for the win. This is also great. Or he kills 2 suspicious people, and he outs himself as scum again because he's the only remaining non-IC. Or he doesn't kill anyone and claims to have been roleblocked. This is also great, because we can move to D5 with one dead scum and no dead townies.
UoS is town -> 10 people alive, presumably two of them are scum, 5 are ICs and one is pretty suspicious me.
Silverspawn is town -> silverspawn kills me and another suspicious person other than himself, scum kills an IC, leaving us with 7 people alive, out of which 4 are confirmed town, one is silverspawn, and the remaining two are the scum. Then you can afford to make a leap of faith and lynch the remaining scum for the win in two days, which sucks for me because I already got vigged in this scenario, but it's great for town.
Silverspawn is scum -> silverspawn kills 2 ICs and outs himself as scum. This leaves us with 8 people alive, out of which 3 are ICs, one is silverspawn, one is a pretty suspicious me, one is the remaining scum, and two more are unconfirmed townies. We can lynch silverspawn, which leaves us with 6 people alive, out of which two are ICs, one is a pretty suspicious me, one is the remaining scum and two more are unconfirmed townies. Mail-mi and DeDe are probably dead and I'm not very trustworthy, which means we lose our investigative abilities. You would probably lynch me D6, which leaves you with 4 people alive, out of which one is scum, one is an IC and two are unconfirmed townies. That's not great, but it's not completely awful for town either. I typed up the possibilities for him killing suspicious townies or pretending to be roleblocked, but then I deleted them because those scenarios are so much better for town that scum!silverspawn wouldn't do either of those things.
For completeness's sake, here's also the hypothetical scenarios where I'm scum:
UoS is town -> 10 people alive, presumably two of them are scum, 5 are ICs and one is pretty suspicious me.
Silverspawn is town -> silverspawn kills me and another suspicious person other than himself, scum kills an IC, leaving us with 7 people alive, out of which 4 are confirmed town, one is silverspawn, and one of the remaining two is scum. You can randomly lynch one of them -> 5 people alive, you can lynch the other one for the win.
Silverspawn is scum -> silverspawn kills 2 ICs and outs himself as scum. This leaves you with 8 people alive, out of which 3 are ICs, one is silverspawn, one is a pretty suspicious me, and three more are unconfirmed townies. We can lynch silverspawn, which leaves us with 6 people alive, out of which two are ICs, one is a pretty suspicious me and three are unconfirmed town. Mail-mi and DeDe are probably dead and I'm not very trustworthy, which means we lose our investigative abilities. You would probably lynch me D6 for the win. Or silverspawn can kill two suspicious people, leaving us with 8 people alive; 5 ICs, 1 unconfirmed town, 1 silverspawn and 1 pretty suspicious me. mail-mi can confirm the remaining town, and then you can lynch silverspawn and me. Or silverspawn can pretend to be roleblocked, which leaves us with 10 people alive; 5 ICs, 3 unconfirmed town, 1 silverspawn and 1 suspicious me. mail-mi can confirm one remaining town, and then you can lynch me, and then you can have mail-mi confirm the remaining two town with the help of chairs and ashersky, and then you can lynch silverspawn.
As long as one out of me and UoS is scum, doing this results in an autowin for town. The worst case scenario is that UoS is town, and I'm also telling the truth, and then town ends up in a 3-vs-1 MyLo with one IC. I'd say we do this.
