Okay, first off, let me start by saying this game is amazing. AMAZING. I'm so back in the world of King's Quest. Its awesome.
That having been said, I think I've played this game/chapter before. It was the TSL demo released back in 2006, with an extra cut scene tacked on at the end, and some bells and whistles added. I was hoping for some plot advancement from what I already knew had happened, but I guess I'll have to wait for the next chapter.
