Klaus had already met Faith for a sparring session. She really wasn't a match for an Original but Klaus was impressed with her skills and he wouldn't be opposed to sparring with her again in the future should she ask.
Klaus had left the hotel and was headed to the store. He was going to pick up some art supplies for both himself and Hope when he saw Faith hunched over. He could hear her heartbeat was racing and from her appearance, she looked as though she had been running. Was she injured?
