Ever since she was old enough to spell her own name, Zoë gets very frustrated when people spell her name without the diacritical on the e.
Zoë always wears her grandmother's wedding ring on a gold chain around her neck. In some scenes The Waiting Game, Zoë can be seen wearing this necklace, which was written into the script halfway through filming.
Zoë has a scar between her eyebrows which she got when she was knocked to the floor by a falling wardrobe, which subsequently landed on her face and knocked her out.
Zoë has a Bachelor of Music Theatre degree, and is also a graded stunt performer.
