Complicated
The relationship between Doug Ross and Helen Hathaway was let's just say, complicated. She was still mad for the countless times he had hurt Carol. He was convinced Helen was treating Carol like a little kid-protecting her from every little thing.
Sometimes it was so infuriating. Take the twins first birthday for example. Doug and Carol had planned a very small party for the girls, just a few friends and family. But would Helen listen? No. she had to go and change the entire plan-inviting twenty more people, insisting that the twins be dressed to the nines.
She's so infurating!
