If Zoë has chosen to continue in her father's professional footsteps during Chapters' Book 1, Adala "Ada" bint Khalid will be her supervisor in a rental bioengineering lab in Propast. Ada wasn't entirely unknown to Zoë before the coma, but a stranger still. When Zoë went to Cape Town university, Ada was a doctoral student in the bioneering department. They never talked to each other though; Ada was perceived as an arrogant and unlikable person. In the meantime, Zoë has reversed her opinion, thinking very highly particularly of Ada's professional capabilities.
