Yuri thinks it is ALL ACCORDING TO PLAN. He is assuming that whatever reaction Gil is having right now is the one Vincent expected him to have and he is purposefully keeping himself distant so the shit can get stirred. Since it's unlikely Oz would have said anything with Vincent there. He thinks Vincent is lurking somewhere waiting for his brother to hunt him down.

So who WAS Yuri... some random noble guys~? Also Vincent's thoughts on spanking, blade/bloodplay, and whipping.
