Katsa will probably be both moving bones and fighting the dogs. Definitely fighting the dogs. She'll not be having a great time dealing with the "greatest terrors" bit of it and will get progressively stressed out as she goes (because killing things is part of at least one issue oops) but will still be doing what she can to kill as many dogs as possible and lend a hand or rescue to anyone who might need it, either Unseelie or Seelie.
