Grey's Anatomy has announced the casting of its first-ever non-binary doctor, played by E.R. Fightmaster. The actor previously made a small appearance earlier in the season and will now have a recurring role for the rest of season 18. This news is seen as a step forward for the long-running medical drama, which has been criticized in the past for failing to keep up with the times. The inclusion of a non-binary character could help the show maintain its cultural relevance and attract a wider audience. Transgender and non-binary representation on network TV has been improving in recent years.
