Sojourner Hooper-Agogô

Sojourner Hooper-Agogô (also called Cousin Ceol) was a cousin of Faction Paradox.

Biography
She grew up in London. As a child, she wore a "pink velour trackie" and was old friends with Maria. She was on-again off-again romantically involved with Ryan.

She joined Faction Paradox by auditioning for a position against several other Little Siblings. This involved Faction-style team challenges overseen by Godfather Starch; after each challenge, another contestant was eliminated. Eventually, Ceol beat Little Brother Dominic to be recruited into the Faction. (PROSE: Now or Thereabouts)

Later, she left Faction Paradox to live a righteous, selfless life, leading an oppressed culture to emancipation, before being forced to do one more job for the Faction. (PROSE: Weapons Grade Snake Oil

Behind the scenes

 * "Ceol" is the name of the island from which the name "Kelsey" is derived; taken into conjunction with her last name "Hooper" and her best friend Maria, it's apparent that Sojourner is a thinly-veiled stand-in for short-lived The Sarah Jane Adventures character Kelsey Hooper.
