Cassia, still rather unclear as to what is going on at the moment simply takes a few cautious steps away from the robed figures for the time being.  She's not really associated with the Captain or Numarra and her hope was that if things started to go bad for her new found friends she'd at least be able to claim neutrality to the attackers, who whould likely be taken in her charms anyway.  The blonde would at least wait another moment or so to see who was likely to come out on top before taking a definitive side!
