Actually, I went through some possibilities; unfortunately, I think our best bet is to try to find the hidden team. It's not ideal, but better than landing in a 2v3 tomorrow. Used to be LyLo; I played around with words, "X or L" sounds nice. Classic X or L scenario and we have to win it TWICE.
There is a possibility (2.4% if all is done randomly) that the remaining scum shoot eachother and we instantly win. But that's obviously a long shot.
A healthy chance ~22% that we still have 4 town tomorrow. (6% with one scum down, 16% no kills)
Equally healthy chance that we end up in MexLo with 1 scum (replacement for Mylo, don't hate it)
slightly less healthy chance (~18%) that we end up in a 1-1-3 scenario which was too confusing for me to analyze but has got to be better than a 2v3.
Here's the downside though:
Bigger chance (33%) that we end up in a scenario with 1v1v2; must NoEx tomorrow and hope scum hit eachother. This sounds dismal, but realize this: a team cannot win without hitting the other, so they're really trying for it. If they both hit the same town, then it just makes it more likely that they'll hit eachother the next night.
