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. She pushed into to the canal thinking she could swim. But when she was in the water,she was drowned by the sons of Rosanna.
