I read that quote, but sensing emotions isn't the same as "I can know every single goddamned thought you're feeling! HA!"I'm relatively sure that early on in the books he mentions that he and the other espers can sense Haruhi's emotions... it'd explain why he always seems to know what she's feeling.
Compare and contrast: "Haruhi feels <emotion>" and "Haruhi is thinking <Thoughts> because <Reason> and therefore she's decided to <action> because of <previous instance."
While he certainly seems to display mind-reading powers, Itsuki has outright said that even he doesn't know what Haruhi is actually thinking, and just makes educated guesses on what he CAN sense, which I think is merely the "states of mind" of Stable and Unstable.
I'm not sure if I should feel repulsed at the idea of a wierd telepathic mind rape orgy in the SOS Brigade, or to squeel at the idea of Itsuki/Kyon.Uh, wait. New thought. gee, Koizumi's connection to Haruhi's mental state gives those 'Itsuki for Kyon' people a bit more room to stand on, doesn't it?
...
What the hell am I thinking, of course I'm gonna squeel. :3
