"That much has always gone without saying." To gain command usually means one of two things: skill has been show, or it is a matter of nepotism. From all of the time that he has spent with Jon, Chiron has always assumed it to be the latter. That that matches well with Daenerys' own abilities is perhaps one of many factors in their relationship.

Chiron's own response is mild, one that's quite prepared to have this entire sport be done. "I believe the matches are coming to a close within a day or two. I may need to rest simply to continue on with our assignment, instead of to fight in the arenas."

If we have won favor, they've made a good show of not letting us know that fact. Which is on purpose, I'm sure. And while I'm sure that we must be some level of improvement over the last time, I follow your concerns. There's a little sigh before Chiron continues. I'm unsure what we can do differently at this juncture in time.
