Cassandra didn't dignify Barbara's comment, she just huffed a little. She just hadn't fully anticipated the strength of the much larger opponent. She could hardly be faulted for such a thing. And unlike her companion, she hadn't tried anything so foolish as to sacrifice the loss of her footing. (What if the giant man had gotten hold of her? He could have flung her away-- or worse!)
Letting Barbara handle the niceties was perfectly fine with Cassandra. It was only when the other girl caught up with her that Cass realized her question was warranted. She sighed, shaking her head. "You lost her?" Well there was nothing for that now but-- "You know how she is; we had better find her before she starts causing mischief..." She released a grappling hook and began sweeping upward.
