Oh Baby - Season 1 Episode 11 Friends and Doctors
Overview: Dr. Bryant runs into Tracy and Charlotte at a restaurant and Charlotte shows interest on him, which concerts Tracy. She doesn't want her best friend and her gynecologist to get involved like that, so she lies to them both about each having commitment issues. Nevertheless, Charlotte and Doug engage a quick romantic/sexual thing, which ends when Tracy accidentally tells Dr. Bryant Charlotte will be breaking up with him. The three end up on non-speaking terms, but Tracy's ultrasound exam brings them close together and gives the word ""family"" a new meaning to Tracy.
