I had one game where my helot MC had raided House de Merre causing Horion to not reveal anything worth befriending him over. So my MC held Horion hostage and sent Linos off to deliver the ransom. When it became clear that no ransom would be forthcoming, my MC chose the option to release Horion. I never heard the fate of either of them again that game. If they are supposed to die at that point, the text never showed up for that playthrough.
