Isabella (The Vampires of Venice)

Isabella is the daughter of Guido. She was sent to Rosanna Calvierri's school to become a bride for Rosanna's sons,not that she knew this. She wasn't as far in the transformation as the other girls. When Amy went under cover as one to open the trap door for the Doctor, Rory and Guido, she met Isabella on the way there. When the Doctor and the crew were trapped,Isabella showed them the way out but couldn't make it out because the sun burnt her skin even though she wasn't a full Saturnynian yet. Later, Rosanna deemed her a traitor, and punished her by pushing her into the canal. Thinking that the aim of this was to drown her, Isabella swam for a brief moment. Seconds later, however, she was pulled under by Rosanna's children, and was presumably devoured.
