Camilla did kick Simmons' ass, making the latter pissed at her. Simmons is a talented surgeon and Camilla doesn't doubt that he will do good in his profession, but unfortunately, his head is so big that it couldn't fit inside the operating room making everyone irritated at him.
He has the brain and the face but his personality is similar to garbage. It wouldn't take long before his arrogance would pull him down the drain.
Dr. Ellis was impressed that Camilla managed to explain to him and in front of the other residents how Dr. Ellis ended up with Peter Grymes' diagnosis. It was a complicated and tricky case yet Camilla managed to solve it within the day that landed her a position beside the operating table holding the scalpel to cut off Peter Grymes'.
That case was her second solo surgery in two weeks.
