- At the start of the game, the Twin is assigned a player, who will be their twin.
- - Any actions directed to one twin will be redirected to the other.
- - Mafia shooting Twin1 will instead shoot Twin2, vice versa.
- - Doctors doccing Twin 2 will instead doc Twin 1, vice versa.

In fact, if a role has no apparent win condition, then you assume it to be another "thinks itself blue, wins as blue" role. Is it that hard?
