Lola (The Shape on the Chair)

From Tardis Wiki, the free Doctor Who reference

Lola was an orphan who lived in an orphanage operated by Mrs Hatchet.

In 1852, her younger sister Rosie was seemingly eaten by a monster from her nightmares - something which later turned out to be an illusion. With the Tenth Doctor's help, Lola discovered that her sister was still alive, and managed to rescue her. (PROSE: The Shape on the Chair)
