I won't vote to execute Sesam and Shamrock Rover.
Don't get me wrong, I'm not accusing her of being 100% Mafia, of course. Gur also doesn't look great, but we can't rule out that possibility right now. If we're right about Gur, trying to execute him won't give us anything. However, if the small probability of the opposite situation materializes, any peaceful vote on him will lead to the execution of an innocent and make our position even worse. Although, of course, it can't get much worse than it already is.
However, for Sesam, it's more than acceptable to leave her vote on Gur, that's true... Because I find it hard to believe that they can both be innocents; there's simply a lack of roles.
