Kelsey Hooper

Kelsey Hooper was the first schoolmate Maria Jackson met after moving to 36 Bannerman Road, Ealing. Her hobbies included drinking Bubble Shock!, flirting, watching TV (especially Hollyoaks and the music channel) and sending bullying text messages to younger children.

Biography
Kelsey was apparently a neighbour of Maria on or near Bannerman Road, as she approached the Jacksons because she noticed the moving vans. Almost immediately after meeting Maria, she suggested they go into town on the free Bubble Shock! bus. The ride was only free, however, because it made a mandatory stop at the Bubble Shock! factory. She and Maria got embroiled in the mysterious happenings there, and soon met the Archetype, who would later come to be known as Luke Smith. She was briefly held prisoner by Mrs Wormwood and used for her knowledge of Sarah Jane Smith.

Although she thrust her way into Sarah Jane's attic, and met K9, she was not involved with the final remedy to the Bane crisis, as she was under the influence of the Bane chemical.

She was later described by Maria as "backtracking like mad — saying there's no such thing as aliens". (TV: Invasion of the Bane)

She presumably moved away from the area some time after the events of the first episode, as she is never again mentioned in the series.
