Juliette Picard
From Tardis Wiki, the free Doctor Who reference
Juliette Picard was a soldier in an alternate Paris who was infatuated with Minski. When he was critically injured, he asked Juliette to kill herself, so he could hide in her body and heal himself. Realising his true nature, she stabbed him and herself, killing them both. (PROSE: The Man in the Velvet Mask)
