I am 100% sure that the Githyanki encounter is going to get re-worked. Its got way too many problems and reactions that make little sense. Having the Dragon present breaks the encounter in so many ways and having the Kith'rak just leave instead of making sure the encounter - with the people who have the thing he was sent by Vlaakith to get - are properly taken care of is bewildering.
As many people have pointed out its a highly problematic encounter. Call it bad design but I think it would be more accurate to say it's simply unfinished.
You know, I was having the same issue with this encounter. "Lae'zel, what is our mandate. To get the weapon. Wait! You were on the ship? Ah. You must have the weapon because no one else got off that ship AND we must kill you now. Dragon, kill them and take it...I...wait what? Oh, we have to leave to tell everyone we have found the item. Hmmm. Oh well. I know its our mandate and all and my dragon could just kill them all in a moment and take it, but... SEE YA"
