Jo is non-binary and uses they/them pronouns and also suffers with hearing loss in one ear. They said in a podcast interview that they attended therapy sessions after training at drama school as they felt a lot of their identity became lost within the training programme and that starring in their first professional show Rent amongst actors such as Tom Francis and Iz Hesketh helped them with their gender identity to identify as non-binary.^[27]
