Goshikuro getting shown up by his lackey would be pretty humiliating for the guy. He may have to put the lackey in his place either way. Maybe the lackey is getting too clever for his own good?

We could say the lackey is foolish or as arrogant as Goshikuro. Maybe his master isn't sure of the lackey's plan so the lackey wants to prove himself and by doing so, he must push Kurama's buttons? This would confirm Botan is important to him but is also confirms to Kurama that there is a student who isn't who he wants others to believe. I do like the idea of Kurama going back to the student, only to find he's not possessed anymore. 

Btw, I'll probably be going to bed in 30 or so, and so should you mister. -wags finger- XP
