[Zevran distantly thinks that he really has no reason to trust Merrill, aside that for all his disappointment in what the Dalish truly were that they were honorable in ways most people didn't know how to be. She never once derided him or called him flat-ears and has definitely acted as a friend to him. So he believes she would warn him if there was a problem, if she knew it.

He also has to trust she would know a threat if there was one.

He takes the amulet from her and inhales. Not quite a gasp, but only his years of training give him that kind of control.

He can see. Not like he did before, but he can.

And were he some other kind of man, the thought of it might make him weep.]

...Ahh, I am so happy that I am able to see when I am in the company of two perfectly beautiful women. [Zevran smirks.]

So, Dagger. What do I need to know about this item that you have yet to tell me?
