If Rynn thinks Alice is irrational, then it's highly unlikely that he'll ever be capable of constructive dialog with a Lurian. Alice is played pretty cool by Lurian standards. And, well, it doesn't help when one sovereign proposes to end a war by suggesting that another sovereign spread her legs for a little baby-makin'. Malus would've burned Dwilight to the ground just to get to Rynn. If Alice was making his life difficult as a result, I'd say that's fair.
Too bad nobody's trying to spread Malus' legs.
