Mira didn't add anything to the conversation, leaving Gwen and Kent to discuss their business amongst themselves, and sticking close to Sae and Travis.  Normally she would have been nervous at seeing Sae's knife out so casually, but just now she was comforted by it, in spite of the looks they were getting as they approached the summons.  She felt better being with a group, even if they might have their differences in opinion.  A group would most likely make a better impression than several individuals striking out on their own, and good impressions were a good thing to capitalize on, especially after their near run-in with the templars.
