I didn't figure Khaludh had anything to do with this. I don't know him well but he is the most like a younger Galiard I have seen on the FEI and while young Galiard wouldn't get in bed with Steel, he could feasibly get into bed with Zonasa.
This will largely be a test of Galiard's diplomacy and Norrel's generalship. Both probably have to do pretty well now.
