NBC’s “Chicago Med” is adding to its burgeoning cast in Season 2. After casting Ato Essandoh as Dr. Connor Rhodes’ new mentor and “Chicago Fire” alum Jeff Hephner as former firefighter turned medical student Jeff Clarke, the drama series has cast Dr. Daniel Charles’ eldest daughter.

“Undercovers” and “90210” actress Mekia Cox will play Robin Charles, the daughter of the Chief of Psychiatry at the Gaffney Chicago Medical Center, according to The Hollywood Reporter. She followed her father’s footsteps and made a career in the medical field.

Here are five things you should know about Dr. Robin Charles:

1. She Has A Strained Relationship With Her Father

An epidemiologist by profession, Robin Charles has a complicated relationship with her father. She will be called to assess a difficult case at the hospital. This is the first time one of Dr. Charles’ (Oliver Platt) family members will make an appearance in “Chicago Med” Season 2.

2. Mekia Cox’s Character Is Introduced In Season 2, Episode 4

Don’t expect Cox’s character to make an entrance soon.

3. Dr. Charles’ Eldest Daughter Will Romance A Doctor

Robin Charles will be romantically liked to the handsome Dr. Connor Rhodes (Colin Donnell). However, their romance won’t start until much later in Season 2, “Chicago Med” executive producers Andrew Schneider and Diane Frolov told TVLine.

However, they do start working as colleagues very soon.

4. Robin Is An Intriguing Personality

“[Robin is] very smart and wry and rebellious. She’s sparky,” Frolov told TVGuide.

5. Her New Romance Isn’t Accepted By Dr. Charles

Dr. Charles isn’t very happy to learn about his daughter’s new boyfriend. In fact, it stirs up mixed feelings in the Chief of Psychiatry. “Connor does not come from a happy family life, so Charles will question Connor’s ability to have a healthy relationship, having not seen one growing up,” Frolov told TVGuide.

“Chicago Med” Season 2 premieres on Thursday, Sept. 22 at 9 p.m. EDT on NBC.
