[ Istredd's gaze never moves away from Yennefer, not because he's trying to stare her down, but because the two of them are in the middle of a conversation no one else can be a part of. He does snap away when both Stephen and Thancred speak; he doesn't need to hold her gaze to talk to her, he was just distracted. ]

You two should prepare yourselves. I suspect you know what to do. Please be careful.

[ Travel light, don't be suspicious, be as safe as possible. They're both intelligent and skilled men, he suspects they'll be safer than he and Kyle are about to be. Although who knows what road they're going down, and if it won't have dangerous steps too. The point is that they have to take the risk on both ends. They'd been thinking for quite some time this could be a possibility. None of them are new to adapting in the face of danger. ]

Thank you for alerting us, Thancred.

[ Otherwise none of them would have been prepared. He knows that pushing Yennefer again in front of all of them is a bad idea so he steps up to her instead. ]

May I have a word with you?

[ As if there is a choice for her, as if he doesn't intend to find her if she leaves the library and have it out in person. Whatever it takes. The others probably are ready to move with what knowledge they have.]
