Izzie's delight about her midday meal has worn off and she mopes as the interns all try to figure out what's up with Patient X. They finally come up with an answer -- that the LDH must be a false positive, and she's totally fine! Everyone begins to babble happily but Izzie screams at them, "She is not fine!" She details how Patient X had visual, auditory and tactile hallucinations (at least she was doctor enough to not admit to the ghost sex) about her dead fiancée. She repeats that the patient is not fine, and the interns are missing something, not looking in the right place. Yeah, what they're missing is that it's totally Izzie, because it's not rocket science to realize that a 29-year-old female with a dead fiancée who has been acting like a loon is standing RIGHT IN FRONT OF THEM. I am getting so tired of all of the suspension of disbelief that this show is asking of its viewers. In general, people are sometimes at least marginally smarter than all of these characters, at least enough to notice really obvious connections like this one.
Meg is horrified to learn that what they found during Tricia's operation was in fact cancer, but the doctors reassure her that since they caught it early they probably got rid of it. She's shaken because Tricia just had an endoscopy a few months earlier, and she's reminded how fast-moving and aggressive this cancer is. Cristina interrupts to say that taking out her stomach saved Tricia's life. This jolts something in Meg, who turns and informs her brother that the reason Tricia runs their lives and plans everything is because everyone else in their lives is dead. She then turns back to the doctors and demands to have the surgery right now.
After Beth's vitals are under control, Hunt and Arizona talk about how her coding while she seizes makes no sense. Alex explains that she coded before she seized, but Hunt is not totally convinced that's what happened since Beth has no history of heart problems. Arizona goes so far as to condescend that doctors can panic during a seizure and imagine things, which riles Alex who maintains that he didn't panic. He wants to do some sort of test that apparently involves shocking Beth's heart, but Arizona won't even consider it since she thinks the heart is healthy. But Hunt seems to be considering the option, much to her surprise, and he muses that if Alex was right it would explain her coding. Arizona points out that if he's wrong they would kill her, but Alex yells that he's not wrong. Hunt, then, makes it Alex's call as to if they will perform the test.
