Conner gets the feeling that the drow are guarding something, and that the two reclining on the bench are surely helping the two obvious guards.

Neither Gryfe nor Nick hear the drow, as they are not speaking. Gryfe can hear many interesting, and in some cases stimulating, conversations and sounds from the patrons, but nothing of any real value.

As Gryfe draws his sword, he sees one of the drow make a very slight, but obviously deliberate motion with his hand.
