Kyle Richards’ biggest regret from 15 seasons of The Real Housewives of Beverly Hills remains the season-one limo confrontation with her sister Kim Richards. More than a decade later, she says the scene still brings her to tears and reflects a family crisis she would handle very differently now.

“In season one, in the back of the limo with my sister, the world saw a traumatic family dynamic,” Richards told The Hollywood Reporter in an interview published August 3. “I still get teary watching it.”

The moment aired in the first-season finale after Taylor Armstrong’s birthday event. During a heated argument, Kyle called Kim “sick” and “an alcoholic,” then added, “I’ve said it now, and everybody knows.” Kim later confirmed her alcoholism during season two.
