Maria Jackson

Maria Jackson was a young neighbour and ally of Sarah Jane Smith.

Biography
When Maria was thirteen, her parents Alan and Chrissie Jackson divorced. Alan and Marie to 36 Bannerman Road in Ealing. That night Maria made the life-changing discovery of a neighbour, Sarah Jane Smith, conversing with a glowing winged alien. The very next day, she and a new friend from the neighourhood went to the Bubble Shock! factory, encountered other, unfriendly aliens and with Sarah, Kelsey and a young artificial Human, Luke (at that time known only as "the Archetype"), banded together to defeat the Bane invasion. (SJA: Invasion of the Bane) Some time later, at school, she met the "cool" Clyde Langer, who joined with the others. (SJA: Revenge of the Slitheen)

After a number of other adventures, Maria helped Sarah Jane after the Trickster made it so that she had never existed. (In this reality, Luke also did not exist.) With the original timeline restored, however, Maria's father stumbled in on the existence of Sarah Jane's activites. (SJA: Whatever Happened to Sarah Jane?) Alab told Maria that she was moving. Alan recanted and decided to stay in their old home. (SJA: The Lost Boy)

During the Dalek theft of Earth, Maria was staying in Cornwall with her father. (DW: The Stolen Earth)

When Alan got a new job offer in America, Maria and Alan made the decision that he should accept the offer. (SJA: The Last Sontaran) Though she has moved away from Bannerman Road, she stays in contact with Luke via email. (SJA: The Day of the Clown)

Donna's World
If Donna Noble had turned right for a job interview instead of turning left, Maria would have investigated the Royal Hope Hospital with Sarah Jane, Clyde and Luke. Since, as it was moved to the moon, the oxygen ran out it caused every one in the hospital, including Maria, to die of suffocation. (DW: Turn Left)

Personality
Maria had a patient, tolerant personality and also an inquisitive one. The divorce of her parents made her somewhat moody. Maria seems much less worldly-wise and trendy than Clyde though she was also braver and more sensitive. Clearly, Maria looked up to Sarah Jane. Sarah trusted her more than anyone in the world.
