Guild Wars 2

Is this a bug?
My character is Sylvari, and I’m on the part of the Mirror Mirror personal storyline quest where you are given a “choice” to take the problem to Trahearne, or accept the Asuran NPC’s help. I am trying to accept the Asuran option, but it keeps circling back to Trahearne, regardless of my choice. Is this a bug, or is this intended?
If it’s intended; why make it a choice? I think that’s really insert crass term for "*not very nice* here if it’s intentional.

OK. I feel silly now. I redid the mission to get a screencap of what I was talking about.
This time, I had a different camera angle and could see that I also had an option of talking to Larra. I thought before that I could only talk to Carrys, and that I would make my choice from her options. I got it now. I need to talk to Larra herself, so I can make that choice.
