Caroline "Caz" Hammond was the ex-fiancée of Kate Connor and a former serving soldier in the British Army. The two girls met in April 2015. Theirs was a whirlwind romance, becoming serious on their second date and they soon became engaged. Caz returned to Weatherfield the following month to spend the Christmas week with Kate before she left on New Year's Eve for her posting in Cyprus, but came back for a short visit in February 2016.
