Carla Morgan was a female human who lived in an alternate version of Earth created by the Trickster. In her world, Morgan was born in 1951, the same year as her friend Sarah Jane Smith. In 1964, Smith fell to her death from the edge of Westport pier on 13 July. Morgan was affected by her friend's demise and continued to think of her for decades. By 2005, she had posted a poem titled An Ode to Sarah Jane Smith on her personal weblog. Carla Morgan was also noted for her love of kittens, which she displayed everywhere on her blog.
