Maria Jackson was a 21st century Brit who initially lived in Ealing, before moving to the United States. She was friends with Little Sister Ceol (then Kelsey Hooper) as a kid, and they stayed in touch after Maria moved. They once met up for drinks on the South Bank, and Ceol told Maria about her initiation into Faction Paradox — although she translated it into business-related terms. (TV: Invasion of the Bane, PROSE: Now or Thereabouts)
Behind the scenes Edit
Maria Jackson originated from and was a main character of The Sarah Jane Adventures. Much more detailed information about her non-Faction Paradox appearances can be found at the Doctor Who wiki.
