Hard of hearing rather than deaf, Leclerc learned ASL at age 17, before she was diagnosed at age 20 with Ménière's disease which runs in her family. She developed a deaf accent for her role as Daphne, but speaks without it briefly in a scene in season 1, episode 9 where Daphne dreams the switch never occurred, and she was raised as Bay Kennish and retains her hearing. She also speaks without the accent through almost the entire episode 15 of season 2, "Ecce Mono", which is an alternative reality in which Daphne was raised by the Kennishes from age three and got a cochlear implant.
