I think to myself why wouldn't Quinn be here? and it occurs to me that this might not be who she seems. While she turns to look towards the gate I take a look at her ear to see if the scar behind it is present. Only one who knew Taras well would know about the scar, If this woman is an impostor, as I suspect, the scar would not be there.
(EDIT: I want to clarify that Eidos is only looking at her ear, he does not actually touch it. With her head turned he can easily see behind her ear as most female druids keep the hair cut very short.

"Yup, sure enough it's the real Taras, you then realize that Quinn is her nickname for Quinntessa who happens to be the owner of the castle."
