Okay, this is from a circle called Sannasubi titled Shadows in Silence. I found an English scanlation on MyReadingManga. It's a little vague but it seems Kakashi and the 3rd Hokage were discussing the stability of the seal on Kyuubi in relation to Naruto's stress level and emotional stability. Because of this, for some reason, Kakashi seems to take it upon himself to torment Iruka who is a "precious person" to Naruto to condition Iruka to become a trigger for Naruto's instability. .....yea, that's what I read, don't ask me how that makes sense. ::shrug::
Go to myreadingmanga.com . There's an English scanlation for it there. It's not very clear on a few plot points though, so you have to sorta figure out the gaps in conversation through context.
