You two should have jointed, joints are much more fun.
And I'm fairly certain you said you could overturn the lynch, by saving someone and choosing who else is lynched instead? May have just not paid close enough attention.
That's how governor works anyway, they are allowed to overturn a lynch one time during the game, they can't stop a lynch (i.e. save somebody but not choose someone else to kill) and they're allowed to overturn from themselves. Of course it can be modified for different games but that's a general governor.
