I should add that it would also be unusual for a Ynysian to poison anyone.  Not because they're morally advanced or anything, just that they live sufficiently far north that they don't really have access to good poisons.  ;D  Culturally, they condemn poisoners, furthermore, as cowards - poison is a weapon for weaklings.<br/><br/>And it would be specifically uncharacteristic of Octavian.  No one has ever accused him of being a poisoner.  A fratricide?  Yes.  A patricide?  Yes.  But he seems to prefer to do his murdering with steel or in war.  Probably not because he's above it but because he's never done it before and because, if discovered, it would make him look bad.
