ER wiki

Tess Ross is the daughter of Carol Hathaway and Doug Ross. She has a twin sister named Kate.


Tess' parents are Carol and Doug. Before Carol realizes she is pregnant, Doug leaves. Making us believe she is going to stay in Chicago forever, Carol briefly dates Luka after Tess and Kate are born, but the relationship never really goes anywhere. After Carol tells Luka she is leaving, we get to see her reunite with Doug in "Such Sweet Sorrow".


  • Tess was born first via a natural birth. No epidural or painkillers, unlike her sister Kate, who was born via C-section.
