Dialog error in Makoru's presentation of the Isle of Kin

While about to sail to the Isle of Kin, I got the following presentation dialog by Makoru: "I can't believe you killed the Kin Tyran."

I believe this is supposed to play after you complete the isle, but I had never set foot on it before.

I'm not sure what caused this. I did the isles in order of levels, so the Isle of Kin came rather late.
