When Collin saw her he knew immediatly what she was.  "Sarenui."  He said, again in the high elvish that only the oldest and most influental familes spoke, or those who wanted to get in with them, on the off chance this woman spoke elvish.  The word translated into what would probably get him slapped in the face if she understood him as it meant something like prostitute, though english didn't have a term derogatory enough to equate.  He found himself watching her face for a reaction for some reason.  Something about her face, he couldn't place it.  "Who is your... companion?"  He said to Bob in plain English.  He only spoke in high elvish when he wanted to insult people.  Prostitutes usually fell into that catagory.
