Luka walks into Mr. Arnold's room. The patient asks whether what he's been experiencing are, in fact, anxiety attacks; Luka says he can't say for sure, but that Mr. Arnold's cardiac enzymes are normal, and that he's not seeing any irregularities on the EKG. Reassured, Mr. Arnold says he didn't think the problem was in his heart. Luka suggests that it might just be that Mr. Arnold is "overly stressed," and Mr. Arnold chuckles ruefully and says, "I could have told you that without the tests." Luka says he'll still have to monitor Mr. Arnold for another six to eight hours, since damage to the heart doesn't always show up in blood work right away, and that, considering the way Mr. Arnold came in, they need to be sure that his heart isn't the cause. Mr. Arnold says that he's sure he just got himself all worked up, and says that she (his wife, we may safely assume) is driving him crazy, and that he never wanted a divorce. He then starts to cry, which is actually very sad. Luka pulls the curtain around the bed, and Mr. Arnold says that every time it hits him that he's getting divorced, he doesn't know what he's doing, and that every day there are more phone calls from her lawyer, more threats, more demands. He says he doesn't know what he did wrong, and that he loves their son and still loves her. Poor Mr. Arnold. He apologizes for breaking down, saying that it's not Luka's problem, and Luka tells him that it's okay, and that maybe he can get a psychologist to speak to him. Then the heavens open up and shine sweet light on my face. I mean, "Luka smiles."
