I'm not sure if this applies to all quests but...
I finished the first good quest. Then I started the second good quest by "ask annora missions"
I then I got a Goru-Nezar head, and returned to Annora.
When I typed "ask annora missions" again, no message displayed (because it already had before).
So, if I didn't already know I had to "ask annora head" next, I wouldn't be able to get the initial message to redisplay.
I don't know if this applies to other quests/missions in the game that once an NPC gives a message and there is a next step that message will no longer be displayed, but I just thought I'd throw it out there.
This is how the textblock is coded in this case. 2nd good quest is the only alignment quest where asking annora missions is a required step. So once your flag has been set to the next step, you won't get a responce from her again.
Yeah I noticed that, just figured I'd throw it out there because it's a minor something that probably should be "fixed" one day.
