Spanish maid (Turn Left)

In an alternative universe, a Spanish maid worked in a hotel outside of London where Donna Noble, her mother and Grandfather spent Christmas. She watched the news when the Titanic destroyed London and said there was something on Donna's back. However, because she only spoke Spanish, she said "tienes algo en tu espalda", which would translate to "there's something on your back". No one could understand her.

Her actions caused Donna to look at her back in the mirror and get a brief look at the Time Beetle. She saw the mushroom cloud above London. (TV: Turn Left)
