Kayla is a vampire. She is sired to Skye who trained her to be one of the thoughest counter-spies on The Anconi.
Kayla was a young woman who Skye encountered. She was pregnant when she crossed Skye's path, which kept Skye from feeding on her. Skye took her in to her hotel. Kayla gave birth 3 months later in the pressence of Skye. When Kayla had given up her daughter she was devastated. Skye had grown to see her as a friend, but refused to stay because she was dangerous to Kayla. However in her emotional state after giving up her baby, Kayla begged for Skye to stay. Skye ultimatly granted her wish, which was to learn from Skye how to be stronger. Skye granted her vampirism and embraced Kayla as a friend for the first time since separating from Alyssa. Kayla tried her best to fill that place, and she put in extra hard work. She caught anything Skye threw at her (literally) and went on to become Skye's protegé.
Kayla is good in deceiting people, but her real identity if pretty quirky and enjoyable. She has a great willingness to learn but can be somewhat over-enthousiastic. Kayla is very used to getting what she wants, and if that's a lazy afternoon nothing can get her off the couch.
