What now? Cassie thought, hearing the howl. Was a wolf coming this way? Why were people showing here when Chrystella wasn't even here? Feeling somewhat paranoid she shifted forms, growling af the intruder, while listening for an approach, just in case the howl wasn't friendly.

she didn't know what she could do by berself, injured, but she would do it. She would prove she could protect herself. 

Or at least not get killed. Essentially the same thing, really. She let out a long, piercing howl, waiting for the introducers answer.
