Jo

 is initially David Brittlesbee’s assistant and, at the time the Raven's Banquet expansion is published, Mythic Quest Studios' newest employee. She is naturally attracted to power, and upon realizing David has none, she gravitates to Ian. By the time of the new expansion's early pre-production, though, she has become Brad's assistant.

Determined to be the perfect sidekick, she jumps full-bore into action like a valiant warrior.

After quarantine
Soon after the team returned to work following quarantine, Jo moved to Brad from David. Though a professional change, the three seemingly treat it as a kind of "romantic triangle", with David eventually devolving into a kind of rejected lover around them.

Brad's mentoring of Jo is along fairly brutal lines. He believes that, if he's trained her properly, she will "try to devour him". She gleefully accepts this as a truism and expresses relief at having escaped from David's mundanity ane weakness.
