** I guess below are spoilers, but, not really since the ep has already been aired on regular tv
Christina put her name down for all of Burke's surgeries I believe, but there was one in particular which Bailey put her name down for first and told Christina to tell Burke, but Christina wiped Bailey's name off and did the surgery instead.
Bailey saw that her name had been wiped off and was really offended..she thought a) that Christina had told Burke and b) that he crossed her name off intentionally (because some of the doctors thought that she was being really relaxed with all her interns (and therefore responsible for denny's death) and so Bailey thought he felt this way too)
But at the end of the ep, she saw Christina doing shit all over the boards again so I suppose she's figured out it was prolly Christina
