At the hospital, Dr. Coolidge examines her as Emma explains that she is seeing sounds as colors. Dr. Coolidge explains that there's a rare medical condition, synesthesia, where individuals have their senses mixed. She points out that Emma is using her deafness to shut people out and argues that it's not healthy. Emma admits she doesn't want others to pity her.
Dr. Coolidge goes to see her daughter and asks her if she still believes she is suffering from synesthesia. Emma tells her what is happening and Dr. Coolidge says that she believes Emma is suffering from Hysterical Blindness. She says that Emma has shut herself away from the world for so long that now she is craving attention. Emma denies this and Dr. Coolidge expresses her disappointment that Emma is wasting her time in the file room instead of treating patients. She tells her daughter that the Chief has offered her a residency but Emma refuses it. Dr. Cooldige then tells her to stop grieving Christopher, as it has been six years since he died. Angry, Emma leaves.
According to her older brother's Assignment Tracker 2.0 profile, the family lived in Missoula, Montana for a time. Dr. Coolidge's parents were employed as music teachers, but neither parent possessed an evolved ability. Additionally, the profile notes that her brother's "primary intimate relationship appears to have been with his sister".
- According to the casting call, Dr. Coolidge was originally named "Dr. Cambridge". She is in her 60s, and is described as a "kind doctor in a NYC hospital. Compassionate and knowing with a vested interest in her patient."
- According to writer Howie Kaplan, "Chris is Emma's uncle. Her nephew, Christopher, was named after him." It was soon revealed that Dr. Coolidge and Chris were siblings.
