If we are looking at these three then the optimal route I think is to shoot ChopBam today and hope to kill, you will attempt to ping Orange N2 and if he's the Mirage Tank it should now work since his disguise is lost, and depending on the N2 result then we either lynch Orange or TheIrishman.
Are we so sure Shade isn't the last one though? Voe may have had it right here drawing out a defense.
