[Nisei's jab at Ritsuka makes Soubi's blood boil; it's a physical pain that comes with any threat to his master. Ritsuka may have started out as his master only under Seimei's orders... but he is so, so much more than that now. Soubi doesn't know how to rationalize this with himself and has no desire to try. The point is, at the moment, that Nisei is stalking Ritsuka under Seimei's orders. He takes a step forward again, his weight unconsciously settling on his back foot as if he's readying himself for a battle.]

What do you plan to do to him?

[It's a very devious question, in a way: Soubi is unable to ask even the most minor details about Seimei's plans, for a Sacrifice's agenda is not for a Fighter to know or to worry about. But Nisei is a Fighter too. His plans are not off-limits, and they are more likely than not plans given to him by Seimei.]
