...that it was just a big gloating trip, in the manner of "haha you just killed everyone you love and have gone mad." I don't know whether Ishy was mad at this time, but it is the sort of thing you would expect, i.e. I may be mad, but not THAT mad, along the lines of Rand, when he talks to Lews Therin. Either way, I thought the whole thing was just Ishy gloating over sending his greatest enemy crazy.
