Simple. If cult successfully recruited last night, then town's already lost. Our best plan, therefore, should be one that ignores that possibility and assume only one cultist is currently alive.
Under those conditions, our best move is to force mafia to kill the cult leader for us. By no lynching, he absolutely HAS to kill the cult leader, rather than killing a townie, because he'd lose otherwise. If RR is actually mafia, then he'll be forced to kill who he ACTUALLY thinks is the cult leader, rather than trying to manipulate us into a mislynch toDay. If he IS the cult leader, he'll die tonight and then we'll either have 2 townies, 1 recruit, 1 scum in the morning OR 3 townies, 1 scum, depending on how the roleblock is used.
This is EASILY our best option. Just do the math and you'll see I'm right.
