Jenny Flint
From Tardis Wiki, the free Doctor Who reference
Jenny was the companion to the Silurian Madame Vastra. They operated from London, in the late 19th century. Jenny and Vastra were romantically involved with one another. She also seemed to get quite jealous when Vastra showed interest in other people, such as when she commented that the Doctor was attractive or when she showed an interest in Lorna Bucket. Among the many allies the Doctor had recrutied, she along with her lover were among the few to survive the Headless Monks' attack. (DW: A Good Man Goes to War)
