Antonio does not really track this, but the 7th-circle wizard reading her thoughts and wearing a +6 headband of vast intelligence has just informed him that this woman seems literally priceless. He's ordered an additional three Security to this location, and for this issue to be escalated to Her Infernal Majestrix at near-top priority.
It's not obvious how Agramunt could really fuck this up for Cheliax, given that eventually they're going to torture her into compliance anyways. But if hypothetically Agramunt decided to lose his temper and kill Merrin and she refused resurrection and Heaven realized what they had and blocked any attempted Miracles to resurrect her anyways, Agramunt's death would take a very long time and when he got to Hell he would still be sad it hadn't lasted longer. Whatever competence Agramunt has, he should currently be attempting to show it.
