Sebastian(?) was about to respond to Aqua in a manner that was almost guaranteed to not be satisfactory to her, when Shara began to move back, and challenge Aqua with knife drawn. At this point, Sebastian(?) decided to cut their losses and try to get some questions answered another day.
They began to move back, counting ont Shara attacking Aqua, and things spiralling out of control from there to provide a window to get out. Unless stopped by anyone, they would do just that, staying in human form.
