Who is Dr. Diane Lewis on ‘Station 19’? Fans recognize the guest cast member

Dr. Diane Lewis is a psychologist and trauma specialist who appeared in two previous episodes of Station 19 Season 3, “Something About What Happens When We Talk” and “Dream a Little Dream of Me.” When she first came to the station, it was for a “critical incident stress debrief.”

The grief counselor was once a smokejumper, so she knows what it’s like to lose someone in the line of duty. In one session with Jack Gibson (Grey Damon), Diane opened up about why she changed careers. After a rough drop from a helicopter, she shattered her leg. Her team rescued the fallen smokejumper; however, a family lost their house and dog in the meantime.

Diane explained that the dog’s barking and the children crying hurt more than all of the extensive surgeries on her leg. She finally talked to someone and realized she wanted to become the person who helped her. 

Dr. Lewis appeared in one other episode of the Station 19 Season 3 cast. However, it was only in Andy Herrera’s (Jaina Lee Ortiz) dream.

Before Tracie Thoms became Dr. Diane Lewis on Station 19, she was Roberta Gibbs on Grey’s Anatomy. According to the fandom, In Grey’s Anatomy Season 15 Episode 6, we met Roberta as she gave instructions about her funeral. However, in an unexpected turn of events, one patient died, and a liver became available for Roberta.

However, the patient was cautious since she already had many surgeries. Roberta continued to talk about her funeral until the moment she headed to the operating room. 

Jo Wilson (Camilla Luddington) and Miranda Bailey (Chandra Wilson) performed Roberta’s surgery to give her a new liver. The surgery was a success, and Roberta lived. However, in the Grey’s Anatomy spinoff series, she became an entirely different character of the cast on Station 19.
