Synys looks between the naga and centaur a little oddly as they talk to each other.  She has no idea if the serpent creature had sensed it, but she certainly hadn't been the one who opened it.  She stays silent as if doesn't bother her - enjoying being overlooked with her set of skills.  Instead of continuing on focusing on the others around her she turns back to look into the passageway with dangerous curiosity before walking in.  The kitsune walks no further than the edge of the bridge for now, but her eyes are drawn to the writhing shapes she's soon able to recognize the origin of.
