Normally an invitation to have sex immediately would send Mark to the designated rendezvous site faster than an Olympic champion. But when Callie orders him to the on-call room, he sulks in a chair and tells her he's not in the mood. She's as surprised as anyone, given that it's probably the first time he's ever spoken those words. She tells him he's always in the mood and, shocked at himself, he breathes, "I know!" He turns and tells her that one of his surgeries was cancelled earlier. She informs him that he's useless and takes off.

Alex goes to tell Kyra and her family that the heart has arrived but as he gets to the room, Mr. Kyra yells that something is wrong and Alex finds her struggling to breathe and convulsing on the bed. Alex listens to her chest and figures a lung has collapsed and calls for Dr. Hahn to be paged, then orders the family out. But they're too terrified and instead huddle together, begging to know if she'll be all right. Alex stares at Kyra, who seems to have passed out. He begins to pull aside the plastic around her bed. The husband starts yelling that he can't go in and break the isolation barrier. Alarms are going nuts and Alex tries to get Kyra's husband to take their daughters away from this scene. He's been reduced to tears, however, and can only hold them and ask, sobbing, if she's going to die. Alex takes a breath and tells the girls (Jessie and Zoë) that this is a scary part and so they have to turn around. They do, and actually I do as well, since he's putting in a chest tube and that's on my personal "been there, done that, don't need to see it" list. They bury their faces in their dad as Alex gets in, and a hiss lets out the extra air, causing Kyra to let out a cry as she regains consciousness. Her husband cries with thanks that she'll be okay and Alex tells the girls that everything is okay and they can turn back around. Fine, so I have to admit that was really kind of sweet. I don't know what it is about Alex, but when he plays the part of reluctant good guy, it really gets to me.
