If we kill silver, we lose a JK. Jimmmmm's power is damn near useless now it's outed unfortunately. Mine and Ichi's aren't, so assuming silver is scum, we'll have two investigative roles, and one of us is likely to get through (the other is likely to get killed). So, the chances are tomorrow we can narrow the lynch pool even further.
If we kill silver and he's town, then ichi's probably the scum. In that case I'm just dead.
If we kill silver and he's town and Jimmmm's the PR scum, then scum still has a killer and a roleblocker, so neither Ichi nor I is getting an investigative result.
So if we lynch silver, we have a 1/3 chance of getting anything from our investigative roles.
If we kill Ichi and HE'S scum, then we have a jailkeeper, which means I could survive AND get an investigative result, although silver should probably go 50/50 on jailkeeping me or Eevee to get some WIFOM going or something like that.
If we kill Ichi and silver is scum then, again, I'm just dead.
If we kill Ichi and Jimmmmm is the scum ... ummm what happens if the jailkeeper and the roleblocker target each other? OP says those things happen simultaneously, but I don't know what that means. I would think that silver would get roleblocked and I would get killed, but I guess if JK has priority silver could still keep me alive.
Depending on the outcome of the JK/RB thing, this outcome might give us a 2/3 chance of having an investigative result tomorrow.
